I like gaming for fun, which can mean competitive mutiplayer, an immersive story or getting some achievements. Thing is, though, I like being able to do whatever I'm in the mood for, and a certain friend keeps nagging all of us, like "oh, do some matchmaking/team deathmatch, we're going to do this gametype, not this!!!! or let's play custom games, I made this gametype, it pwns!!!!" he's not adverse to complaining either, basically a game type isn't skewed/unfair/poorly made as long as he wins, which sometimes reflects in his custom content.
In other words, I'm really the kind of gamer who, if I get tired of something, I'm done, regardless of the bitching it attracts, though that friend has put me off private multiplayer stuff with my friends.
