So, when I set out to make this list, I figured the best place to start with it would be explaining what my criteria are, just to at least make some sense of the ordering later on. For one, my main points of measurement are inversely proportional, with the two scales being my personal enjoyment of the game and how poor of an experience I feel it would be for what I consider a casual player base. The less I like the game but the better of a casual experience I feel it is, the lower it is on the list. The more I like it and the more averse a general audience might be to it, the higher it is on this list. As for the games that are on here due to no longer being playable, I don't really have a good justification for where they're placed, so it'll be fun to try and rationalize it as I go, I guess. Not much more of a preface needed, it's a fairly standard top 10 list, so might as well jump right into it with #10.
10. City of Heroes
City of Heroes was an MMORPG that released in April of 2004, a whole 7 months before World of Warcraft would release and completely dominate the MMO landscape for the next decade. It's actually the entry I had the most difficulty justifying why I wanted to include it, mostly because it's the one I've played the least of, having only clocked a few hours into it. But I felt it was noteworthy enough for two reasons, primarily because it fits neatly into the "no longer playable" subcategory, but also because I felt like it was a refreshing new idea for an MMO at the time of its release. MMOs have long been represented mostly by fantasy-based settings, with games like Everquest, World of Warcraft, and Final Fantasy 14 being the big ones almost anyone can name as sort of the faces of the genre. For there to be a superhero based MMO that also wasn't based on an existing IP like DC or Marvel was quite groundbreaking for its time, though DC Universe Online would release only a few years later and effectively supplant City of Heroes as the premier superhero MMO.
As for why I can't personally recommend it even if it were playable today, it's mostly because of the monthly subscription model most MMOs push nowadays. This will come up again when I talk about some other entries later down this list, but suffice it to say that I don't much care for having to purchase a game and then continue to pay a recurring fee just to access some of the its core functionality. That said, there's nothing specific to City of Heroes that I can think of that would make it so objectionable that I would never recommend it to anyone, so that's why it's so low on the list; seems like a fine game if it were still available, but MMOs are always hard to recommend.
9. The Elder Scrolls V: Skyrim
This is probably a decent spot to bring up another sub-category of criteria for these games; how much is the base experience worth your time. This means that, for the most part, I'll be excluding add-ons, mods, DLC, and other similar bits of content unless otherwise stated. In this respect, I think I can comfortably say that Skyrim is a pretty bad game. It shares a lot of that Bethesda charm with Fallout 3, being rife with bugs, glitches, freezes, easily-breakable quests, and other game-breaking issues. There's also approximately three voice actors throughout every NPC you talk to, one of which is the studio's notorious head Todd Howard, and all of them are pretty obviously phoning it in because they have about 200 other lines to read in the same faux-Nordic accent. The quests mostly don't ask anything particularly interesting of the player; go here, talk to this person, kill this thing, navigate this dungeon that looks identical to three others you already did but maybe has one or two new traps, loot the chest, repeat ad nauseum. The main story is as basic as it gets, with an evil dragon threatening the world and you, the blah blah chosen one blah blah special powers blah blah kill dragon. There's something about an ongoing civil war that gets resolved in a single conversation by you choosing whether or not you want to side with the Nordic racists or the not-Roman empire. All in all, Skyrim offers an impressively shallow experience for how expansive its game world is, only somewhat salvaged by the player's own agency in how they want to engage with that world (usually by breaking it over their knee and finding the fastest way to max out stealth and archery).
Skyrim is only on this list because while it would otherwise be so uninteresting as to not even be considered, I feel like there's not even much point in even saying I don't recommend it. If you recognize that name at all, you've probably already played Skyrim. You probably bought it more than once. You've probably modded sixteen different ways to kill those annoying children into the game just to get them to shut up every time you walk into Whiterun. For that reason, I feel like it's at least worth recognizing for its near-universality, even if I feel like its defenders are far too kind to it for what it really is.
8. Dragon Ball Xenoverse 2
Unfortunately this is another contender for the least interesting title on this list. Xenoverse 2 is a pretty boring game whose main appeal is making your own custom character to re-experience the story of Dragon Ball with some minor twists for the umpteenth time, and then engaging in online battles against other people who have done the same and seeing whose connection holds out the best for someone to actually land a hit and win. It's not particularly good looking, it plays pretty poorly, and it has an absolutely absurd amount of DLC to the point where you'd think it makes up more of the playable roster than the base game had. The main reason it's on this list is my own personal enjoyment. I really, REALLY love Dragon Ball. It's my favorite series of all time, and any opportunity to get even the tiniest crumb more of Dragon Ball content makes me forsake all previously held standards of quality. So I guess unless you're just as susceptible to nostalgia pandering as I am and are willing to put up with the most repetitive combat in a 3D RPG fighter thing in a long time, please avoid this like the plague.
7. Elden BloodSouls (AKA the FromSoftware games)
I will preface this by saying that these are probably overall the best games on this list, which is why they are so low ranked. They are extremely well-crafted experiences that invoke dark, atmospheric worlds without ever making the player feel like things are completely insurmountable. There's always a way to beat the boss, you just have to figure out if it's an issue of equipment, or an issue of skill. But therein lies the rub; sometimes, it is actually a skill issue, and some players, for any number of valid reasons, cannot or do not want to develop the skill necessary to beat certain bosses, at which point they are likely to become roadblocked and stop playing. This is not the fault of the players, nor the fault of the game developers, but some kind of nebulous concept of difficulty. How do you make a game difficult enough to be a rewarding experience without alienating players who aren't good enough to overcome that challenge? There really isn't a right answer that anyone could come up with, given how subjective of a topic difficulty is, but I think FromSoftware has done an impressive job at giving the player every tool necessary to overcome (almost) every boss in their games without jeopardizing the difficulty of the game.
All that is to say, these games are ones I could easily recommend to almost anyone, with the caveat that they will sometimes be brutal and feel unfair. There will be a time when a boss feels cheap, like you don't really get what you're supposed to do, and that repeatedly slamming your face against a wall isn't worth your time, and you'd be right to feel that way. All I can say is that these games offer some of the most intense, satisfying, and heart wrenching moments I've ever experienced in a video game, and nothing has come close to overcoming a challenge that just moments before I had considered beyond my own capabilities. These games made me want to get better to beat them, but I also understand people who may not adopt that same mentality, and for that reason they all felt deserving of a spot on this list.
6. Touhou 11: Subterranean Animism
This one may require the most preface out of all the entries on my list, but I'll try to keep it brief. Touhou is a franchise that centers primarily around the bullet hell genre, a genre classically defined as looking something like this:
As for my reasons not to recommend this game, the difficulty discussion comes up again, but also I feel like Touhou is niche even among bullet hells. There's probably not a huge demographic of people interested in bullet hells based around Japanese mythology and culture as represented by cute girls with weird hats, as unfortunate as that is to say. Also, while the in-game work to make the bullet patterns look good is phenomenal, the actual character artwork is... an acquired taste, to say the least. ZUN is a respectable man in that he does almost everything himself to produce these games, but while his music composition and programming skills are commendable, his illustrations can be a bit off at times.
5. Magia Record (The Sacrificial Lamb Representative of All Gacha Games)
While I could go on and on about the predatory nature of gacha games and list off about a dozen other worthy candidates to fill this particular spot on my list, this one I feel is the most worthy to really tear into because of just how awful it was (and still is, if you're for some reason willing to play it in Japanese). Magia Record is a free to play game that has admittedly good artwork and (some) good character voice acting, but that is where my praise for it ends. This game, a spinoff of the anime series Madoka Magica, is designed to do one thing and one thing alone: rob you of your hard earned money. There is no rewarding experience to be had, no moment of triumph to celebrate your hard work, no compelling narrative to keep avid readers invested. There's just a hole to throw money into, and sometimes that hole will show you a pretty picture to convince you that the money you threw in was actually doing something. Worse, it is uniquely offensive as the images it rewards you with are exclusively of young girls, and I believe it goes without saying how this treads dangerously close to some incredibly suspicious territory.
My enjoyment of this game was exclusively based around its ties to the Madoka series, something I would recommend people engage with if they have any familiarity with the magical girl genre at large. That, however, is nowhere near enough to justify any interest in this atrocity, especially given the state of its global version's last few months as it rushed every last piece of content to squeeze each and every penny from its player base before unceremoniously shutting down.
4. Heroes of the Storm
Heroes of the Storm is a multiplayer online battle arena (or MOBA for short) based on essentially every major property owned by Blizzard Entertainment, in the same vain as League of Legends or Dota 2. It features an impressive cast of Blizzard's all stars and a number of varied maps with different objectives to help push players towards victory over the opposing team. Unfortunately, Blizzard has been increasingly cutting support for HotS, and the game is currently in maintenance mode, meaning it is unlikely to ever receive any more new content or balance updates. With its dwindling player base, the game is effectively dead.
However, this is also probably the saddest entry on this list for me personally, because I loved HotS in its hayday. Having been a long time supporter of Blizzard (right up until the acquisition by Activision) and a fan of League of Legends, this game was a perfect blend of two of my favorite things at the time. Characters I was already familiar with through having played Diablo, World of Warcraft, Starcraft, and even some new faces from older Blizzard titles like the Lost Vikings made for a game that had nearly infinite replayability, because at any time I could just pick another one of my favorite characters and quickly hop into a match with them. Sure, the game wasn't very well balanced and was dependent on teamwork which made playing without friends a hassle, but to this day I have never had more fun playing a MOBA than HotS. It's such a shame to me that this game was left in the state it was, because I would still be playing to this day if it weren't running on life support.
3. Pokemon Radical Red
