I have a few.
-Changing so much in your remakes that the genre essentially changes. Depends a lot on what's under the hood. Primarily gameplay systems, FFVIIR and RE2R nailed their loops despite being different from their original releases, but sometimes it's just rough. Shattered Memories for instance. Alright game, but in what universe does this have anything more to do with the original Silent Hill than say, the movie Taken?
-incidental in gameplay dialogue. I don't mind it, but I hate it interrupting chill time in games. I hate it giving hints. I hate it being pointless drivel. I hate it being the opposite and having meaningful plot information because it will either got drowned in gunfire or swordplay or it will cut off, and in most cases, fail to resume afterward. Just give me a data log a la Mass Effect. Or fuck, very least, a conversation log.
AI partners in traversal segments. Cool, give me an AI partner or group in battles, whatever. In moment to moment gameplay, though? Nothing more immersive than walking slowly down a creepy dark hallway while your AI partner stops. Runs forward three steps until they're up your ass. Stop. Repeat. Clip into a wall. Get stuck on a corner.
-Open world icon clutter. Enough said, I should think, but as a precaution: This shit is ugly as sin and overwhelming as fuck.
