i always do it for fun, i do get into it and get semi competitive occasionally, but i mostly do it for the adventure and sight of the game.
up until a few years ago thats what i thought games were all about..but i met someone (we are decent friends suprisingly) but all he does, is play games for competition, and im not even kidding, he wont play a single game that isn't competitive, and if it isn't he says how bad it is and how its a waste of time. anytime he loses in anything he turns into this raging troll and anytime he wins he turns into the elitist king, its quite sad trying to play games with him =\ so point of the story is there are people out there that game just to compete, not for fun, or for the adventure, but pure competition.
i garuntee you can guess what games he plays.
