Which gameplay mechanic almost ruined a good game for you???

I may be off topic here but for me the combat in Skyrim is aweful.I generally like the game but man.....I can't get used to the combat mechanics.Oh, I also hate the shooting in GTA4 and Red Dead Redemption.So I sold the 1st one but I did finish RDR cause overally it was a magnificent game.
