-When pausing takes longer than the time you take to press the button (I'm looking at you, Dragon Age: Origins for PS3)
-When they show you an amazing ability in a cut-scene, and when you try it out, is very much dumbed down. (Like when you go to a Mc Donalds for the first time, hoping to get the burger on the picture, and you get something completely different)
-When you accidentally cutoff an NPC talking because you stepped on another trigger, and you keep wondering what would they wanted to say (Portal 2, Wheatly, seriously).
-When you save your game before a big fight, and the game auto-saves automatically (This is not actually the games fault, but it does pisses me off a little)
-When they introduce a new technique or special move that you have no idea how to pull off because the tutorial is badly written/not detailed enough.
-When you save all your 1 hit kill bombs for the upcoming last boss, just to find a not so hidden (or not hidden at all) room filled with ammo.
-When you do get to shoot your 1 hit kill bombs to the boss and they do shit damage because you were supposed to use them in the last wave of enemies.
-When you do something you shouldn't have and the last quick save you did was 20 minutes in. (Again, not the actual game fault)
-When you do something to change the appearance of your character willingly, and the next mission or objective IS to change your appearance (Fuck you, Rider, Fuck you, San Andreas)
-When you only need 1 ruppee/gold coin/septim/silver/zen/bottle cap/any other currency to get the "Best thing ever" and you can't seem to get it, because you're too lazy to back track all the way to the open field to obtain it, so you half ass it and lurk around the city trying to find it.
-When you can't save because it's scripted.
-When mobs are invulnerable to a type of attack for no fucking reason. (DA:O again. Seriously, Skeletons are immune to Nature Damage? Why!?)
-When enemies throw the usual stupid shit like unblock-able spam-able attacks (Those mobs that went underground in God of War 3) or ranged attacks from unreachable places (Because the devs expect you to dodge AND kill the final boss)
-When they add timers on things that SHOULD NOT HAVE A TIMER (Prototype, I KNOW you have a special place reserved in HELL for your final battle)
-When a cut-scene starts and it doesn't exactly links up with what you did.
