List of things I want to do...

Something Steampunk (This is the most nebulous.... I could just do a Steampunk Risus addon and be happy, I think. Steampunk doesn't require as much crunch, for me, as some other concepts like....)....
Something Mech-based (With a Mechwarrior feel rather than a Gundam feel... I like my mechs to look/function like military equipment, not mythical creatures)...
Something Western (Started with Fistful of Frenchmen, hopefully to be revised)....

Something for simple, modular combat, in the vein of Animalball: Melee.
