Mine is that Elden Ring is very overrated, the open world is bloated and the entire thing would benefit from being maybe half as small or at least condensing dungeons/things to do. It has a bunch of random shit everywhere but none of it is compelling or fun to do and basically useless aside from sometimes having good items. They're also almost all exactly the same shit over and over. The weapon upgrade system is anti-fun and keeps you from experimenting with anything new. Many of the quests are basically impossible to do without a guide. The platform sections are trash, though thankfully not too widespread at least. The game just gives you too many random shit items, too. The melee combat isn't that fun either, but that is more of a personal preference I guess. I played a sort of battle mage type character so I had a variety of spells to cast at least. I didn't hate it at all, but by the last 1/4 of the game or so I was just ready to finish and probably would have quit if I didn't feel compelled to beat it. I would say it's a 7/10, people act like it's the greatest game of all time though.

Probably not as unpopular but Jap games (maybe more specifically JRPGs, that's mostly what I've played) in general just have way too much random bullshit. They'll come up with a good gameplay system but add like twice as much shit in it than is needed.
