I nipped this one in the bud YEARS ago, and my campaign has been bettered because of it. Each player has a "pool" of four characters from which to dip from, and they have to choose which one to use for a particular adventure. Then the others all go off and form a total of 4 parties. After each adventure is done, they all return home (assuming they survive, which they usually do) and get mixed up again. It's a lot of fun having different interactions between characters. The only bad adventure turned out the be the one full of people with no motivation... They had to be steered with NPC's since they didn't have a leader. I'll never have THAT group together again.
