I was wondering, a lot of people seem to be DM's or GM's.
I think I see more GM's than players here (And that isn't the average selection of DND players.)
Bit of both was recent more DM than play, now its more play than DM. The balance changes so often that really none of the options you've provided match.
In our group, we switch DMs every 2 to 4 weeks, meaning that everyone has to master.
I must admit I love both - playing a game, creating a character and see how he works inplay, and to create an universe and adventures for it.
I can`t decide what I really prefer...
