What part of a game you enjoy replaying do you dislike replaying?
I love the original Hotline Miami but I'm not a big fan of the boss fights like the ones in Neighbors (Biker) and Deadline (Van Driver). I find it kind of slows down the game and limits the strategies you can take.
Another example would be Fallout 3. I find the tutorial section in Vault 101 can feel a bit long after a fifth run but maybe that's because I was spoiled by Fallout New Vegas' ability to run off in your own direction immediately after leaving Doc Mitchell's house.
I call Nier:Automata "the best game I will never play again" and it's because of 9S' combat.
What were they thinking? No one cares about 9S anyway! But he's your playable for well more than what should only have been his one-third the game, and his combat is AWFUL! If I wanted to play Asteroids I'd play Asteroids. You have two other playable characters, both of which chop up robots with giant swords! THAT'S what people are here for, know your audience!
The 21 other "endings" are just rly dumb imo, except for the one of them that's pretty special but that I would have never encountered ingame without looking at the wiki
