Video game pet peeve?

AND GO!

Unskippable cut scenes right after a checkpoint for a difficult boss/semi-boss battle. I remember playing ME1 where you climb this hill and they drop off one of those huge Geth colossus things and like 7 regular troops and you get two boxes to hide behind. Playing on Insanity that early in the game, almost everything was close to a one-three shots for a death depending on what you got hit by. I think its the mission where you rescue that-one-character-I’m-not-going-to-name-for-the-sake-of-those-who-haven’t-played-it-yet, actually. Right before you enter the underground part. Talk about frustrating.

What have you guys been through that's caused frustration when playing your favorite games? :x
