To be blunt, I have Gamer ADD. As A GM I fear it has been a bane and a detriment to my players. They never get a sense of continuity, never get a chance to build their minions into powerful world figures, and never get the chance to spend more than a month or two tops with the same game.
Flux is the ruleset that I've been waiting for. It's a simple, elegant way to tie together several games in such a way that the players can actually look forward to playing more than one game, or switching between games rapidly.
