IDK about that, but if there’s an old game I find unplayable, it’s going to be for a less cosmetic UI/UX problem, some specific examples are:

• Starcraft - holy shit destroying your mouse just to be “”“good”“” at micromanaging when your dragoons can have nap time and use the bathroom is boring af, take a hint from modern RTS inventions like squads from Dawn of War (2004).
• Diablo - no I don’t to micromanage random inventory things that are fully automated in Guild Wars.
• (IDK some random FPS) you need to press a specific key on your keyboard to pick up ammo and there’s literally no hint anywhere that this FPS requires you to do something literally no other FPS does
• install instructions for windows 10+/OSX/ubuntu/wine look indistinguishable from hacking into the pentagon and also don’t work, or haven’t been updated since windows XP/7/8 but isn’t old enough for DOSBox.
• Gauntlet (2014) - is there some reason 2 players can’t both be the archer? That’s a first for Gauntlet games AFAIK. Also the wizard’s controls is bizarre af so if you try a 4 player game somebody gets stuck the wizard and has no way of knowing wtf they’re doing.
• Mario Kart Double Dash - only one player can select each character. Also, each player has to select 2 characters. So if you’re player 4, you’re kind of fucked because the best 6 characters are probably already taken.
• Civ4 - stacks of doom are really dumb after experiencing Civ5 and hex tiles
• Civ5 - every else was better in Civ4
• Civ6 - districts are stupid and everything else is still better in Civ4
• Civilization Revolution - if you don’t already have it installed, you have to play the microtransaction DLC shitware called Civilization Revolution 2 because CR1 was delisted.
• Continuum - the good maps are empty and trenchwars is ran by a MAGA chud
