Dark Souls 2: SotFS. I actually kinda like Dark Souls 2, but I think I'm upset the most at how it could've been potentially much better without making radical changes. When they announced the remaster (scholar of the first sin), I was excited that they'd go back and fix it. Hot take? They just made it worse.
They made enemy placements a lot worse and more spammy than ever. They hid the DLC keys in annoying areas. They changed a lot of item placements for no reason other than make the game feel fresh, and some of the new placements made little sense. They also didn't remove adaptability or go for any low-hanging fruit fixes.
It was just a bummer. DS2 could've been a lot better.
