Maybe soon?
A current game I'm starting has the players switching between two systems. The idea is that they start as a group of standard psuedo-medieval villagers in a distinctly non-magical world, and find a gate that takes them to D&D-land (for lack of better name at the moment). They'll be switching back and forth as the game goes, with their D&D-land powers slowly bleeding out to give them abilities in mundane-land. Plotwise, two people - one from each world - are trying to force the worlds to merge into each other, plotting to grant themselves complete domination over the combined world. My idea is to set the players up to decide on if this is a good or bad thing, and how to act fro there. If they decide it's a good thing but the two people doing it are evil (and they are evil ;p), there's a good chance they'll usurp them and become godlike powers of the newly combined world.
