I agree totally. We both know only too well that a Star Wars game can sustain itself on its own site.
My thinking here was that this board, and specifically the Clone Wars setting, would be contained enough that we could see whether or not our muses (as a group of players) had the fuel for a larger, independant game. If, later on, we discovered that the spark was still there, we could jump forward to a new site and time-jump in to the Jedi Purge (or something) and allow people to still preserve what they'd done here in the Clone Wars if they wanted. The Clone Wars game wouldn't necessarily just have to end at that point either. Lots of possibilities.
In any event, that's my rough line of thinking. I'm sure in chat we could hash it out more.
Avengers, at best, would have to wait for the movie release to capture my interest. My Marvel muse is just...meh. LOL
