As much as I don't need to be starting a new game, these two ideas have been bouncing around in my head for a while, now, and demand to be heard and played.
1) A Familiar Face. Based on one of the most interesting scenes I've played so far... A man (or woman) finds themselves in a parallel world. Everything's the same, except for a few minor differences. Nothing significant; maybe a different team won the Superbowl one year, maybe a street goes by a different name, something along those lines. Oh, and, as the person finds out, they're already here. As the opposite gender. Which leads to the ultimate question; would you have sex with yourself, of the opposite gender?
2) The Gathering. This one requires a bit of explanation. As I was working on a system for resolving duels for a Harry Potter-esque game I'm working on, I kept getting this feeling of deja-vu. It took me a good couple hours, but finally, I placed it; a game I'd been playing for well over a decade, and was intimately familiar with. And it struck me; why hadn't anyone made an RPG out of this wonderfully detailed, complex, and exciting setting?
Imagine: Two wizards face off, each tapping into and changing the landscape around them, summoning exotic creatures, hurling mighty spells, and leaving the battlefield a smoking ruin, before one finally falls. Sound exciting? Bet you'll never guess what game I'm basing this off.
Magic: The Gathering. Yes, the card game. I'm still working on the design for it, but by combining some of the basics of the card game with the RPG-like computer game that came out about 8 years ago, adding in some freeform elements and giving it all a good mix in the blender, I'm hoping to try out a freeform-system hybrid game. Anyone up for it?
