Me itīs a bit different, I donīt like to play with people who get pissed next to you when you play with them (like throwing the controller, starting to swear or to be mad at you..). Thatīs ....ing childish I think.
Concerning quiting games, Iīve stopped playing to GoW2 after loosing many times against Zeus at the end. 4 months later, I played again, and kicked his ass at the first try
Still didnīt get the last boss at Prince of Persia 3 though, it has been about 3 months I stopped now..
