Not saying that it's not possible, but my point is that, if the entire party isn't on the same page, then everyone's idea of fun is at jeopardy.
This applies for everyone, Min-Maxers, Roleplayers, munchkins, even a group of like minded THOSE guys can have fun when placed in their own element. However, some people just can't blend their play style to the rest of the group (Or, in truly horrific cases, the entire group can't blend with one another), things can get hairy.
I'll use my DM as an example:
While he was able to craft lush worlds for us as a DM, as a player, his one and only concern was combat. Whenever someone else was DMing, he'd completely lose interest in the game until he was given something to kill. And, when he lost interest, he became disruptive.
Pretty much, the only way for him to have fun in a game was your typical "Kick down the door and kill every god damned mother fucker" sort of play, which the rest of the group found absolutely boring.
Cool. Just remember, while we may have different playing styles, at the end of the day, we're all just nerds playing a giant game of pretend
