There's quite a few that weren't mentioned here: - Random encounters in RPGs (especially when the battles take 3 minutes each). - Cheap AI. - Unsatisfying endings (way back in the NES days, you would slog through an unforgiving game for hours upon hours, taking days to finally get through... only to get a static ending screen that screams "VERY THANKS!" at you). Though we didn't seem to mind as much before we were spoiled with better stories. But while I have too many others to mention here, I do have to make mention of one of my biggest peeves in any game, current or past gen: when you die in one hit. Even in the NES days, I hated that. You were the hero, saviour to the entire land... but if a stray pebble hit you, you were a goner. Take Life Force (NES); as powerful a ship as the Vic Viper was, impact with a jellybean resulted in its disintegration. When I was a kid, I never questioned it; it was just annoying. But now, I can't help but wonder about it; a grain of sand touches your fuselage, and you're reduced to atoms? That kind of thing was only made more annoying when a game's levels didn't have any of those hidden "checkpoints" for you to start at when you died, making you overcome ALL previous hardships just to get back to where you died.
