I'm surprised how much of that list I did play. It didn't seem like I'd be someone who'd played World of Warcraft, Pokemon, or Modern Warfare, but somehow I did. And definitely a lot more than either of them deserve if you ask me
Here's the full list of games in the top 200 that I didn't play. I guess that leaves me at 168 that I did. Sorted roughly by how "relevant" I feel the game is, based on its reputation:
X-Com: UFO
Tony Hawk's Pro Skater (Series)
Halo 2
Outer Wilds (literally in my 2024 backlog list)
Persona 4
Persona 5 (P4 and 5 in the list, but not 2 and 3 which are the ones I did play :P)
Papers, Please (literally just fired up the title screen, but I don't think that should count)
Ultima Online (kinda too late for this one)
Zork (at least I think I haven't played it, I'm not sure if my familiarity with it is second-hand or first)
Elite (I might have fired this up in the past and had no idea what to do)
Burnout 3
EverQuest
Baldur’s Gate II (played the first game, and it was extremely boring)
X-Com: Enemy Unknown (been on my backlog list several times in the past, never got around to it)
Untitled Goose Game (bought this for my gf when she was having her "geese are fun" phase, but we never tried it )
StarCraft II
Fortnite
League of Legends
Overwatch (I've seen footage of this game and I have absolutely no clue what's going on)
Dota 2
Fire Emblem: Three Houses
Tecmo Bowl (Series)
Oregon Trail
Gran Turismo 3 (I played the PS3 one quite a bit and really liked it, I feel like that supersedes GT3, doesn't it?)
Stardew Valley (isn't this just Harvest Moon?)
Into the Breach
GTA: San Andreas (why are the GTA games listed separately on this list, they are basically all the same)
Left 4 Dead 2 (played the demo of the first game and found nothing appealing about it)
Rocket League
Red Dead Redemption 2 (I loved the first game, but pretty much everyone seems to agree RDR2 is garbage)
Madden NFL Football (Series)
Tom Clancy's Splinter Cell: Chaos Theory (I thought Pandora Tomorrow was the one everyone liked, I played that one!)
Also I played through the demos of Mass Effect 2, L4D, Dead Space, Destiny, and Deus Ex (and the first episode of Walking Dead), but never played the full games, which I guess still qualifies as having played them. I think Deus Ex so far is the best bet at an actual "everyone should play" game that I for some reason still haven't really played. At the time I guess I was just disappointed it wasn't System Shock 2
Also Tony Hawk and X-Com are definitely games that come off as iconic "must play" titles to me, but they are kinda outside of genres I'm likely to dig. I feel pretty fine not having played the rest of this list.
