"I pretty much never play more than a single campaign with the same group of people anymore. It's so great! I get to custom recruit a new, interesting group of people for every game I put together. Yeah, it can be a pain, but the upside is that I get to play a lot of different games with a lot of different people and don't have to try to arm-twist people into playing games they're not excited about or playing with people they're not excited about. "
And it struck a chord with me. At one time I played with mostly the same people every time through multiple games and campaigns, and now it seems that even the "solid" groups I have still lose and gain players all the time, and I also seem to be building specific groups for smaller games and such.
So what's you experience like? Is it a group of friends who play together all the time, several groups, specific groups for specific things, pick up games, some form of mixture. I'm interested, that's all.
