I don't know about you but I hate it when I have people telling me what to do when I'm playing, my brother was thee worse at it, he'd often constantly tell me obvious things like I couldn't figure it out for myself.
I don't backseat drive people when they play, I'll help if its obvious they don't have a clue, but otherwise I let them deal with figuring something out. Also I don't like spoon feeding someone what to do in a game, my brother would do that a lot too, just ask me what to do instead of spending 5 minutes on it.
So are you a backseat driver? Do you like it when people tell you what to do when you play?
