I like good graphics. I like a good story. I like interesting and varied gameplay. Not a big fan of the battle royale games, or anything multiplayer.
While I would love to see more realistic graphics (particularly human faces which most games don't get quite right yet) , there needs to be some balance. I've played games where the main characters are absolutely beautifully animated, but some of the NPCs are not. I know why it is. Even with a today's computer hardware and game sizes nudging half a terabyte, they reduce animations on minor characters to save space. They may also do it for budgetary reasons, to reduce the time spent creating the animations (and possibly the number of animators).
It's a bit simplistic to say modern games aren't fun. They are like any games. Some are, some aren't. I've enjoyed hundreds of hours of gameplay in some games, an have completed the storyline of some of my games many times. I also enjoy the odd arcade style game I can just pick up and play without devoting hours to completing a mission.
As for speedrunning games. Never seen the point of that. When I buy a game, I want more than a few hours entertainment. But then I've never been interested in notoriety or fame, and don't have (or want) a youtube/twitch channel I am trying to sell, so the fame resulting from speedrunning any game does not interest me.
