Obviously, your favorite game is your favorite for a reason. But since no game is perfect (human error and all that), even your all-time favorite has one or more flaws that take you out of your time and break your immersion. I wanna know what they are. I'm not looking to bash certain games, as everyone has their own tastes. Hell, I'll start with my own favorite game.
The Last of Us, to me, is a finely crafted game that combines story and gameplay in a way that just feels amazing. The combat, characters, interactions, everything to me is just a marvel. The only issue? Your AI companion is almost invisible to enemies. If not for the fact that your AI partner sometimes gets caught in a grapple that you must save them from, the game would've become broken as your partner assists you and never gets into trouble. Granted, if they were always to be seen by the enemy, the game would've been infuriating to play and become yet another awful escort mission. So yeah, there's the only blemish in an otherwise (IMO) flawless game.
So what about the rest of you? What about your favorite game annoys you?
