Right, I probably won't do anything with these for a while, but I would like to get some feedback.
Idea one-the gods of Generic Fantasy World are just chilling. And they get bored. So they decide to have a contest. What follows is rather randomly empowering some people and goading them to fight. Not all of them would be so keen on the idea of just killing one another for the entertainment of some god, though. Further complicating matters are those who DO want to play the game, law enforcement (because battles cause rubble), religions trying to recruit you as their messiah, other chuches trying to kill you, outsiders trying to kill you, people who want to harness your power, etc, etc, etc. Since you're already supah-powerful, would probably focus more on relationships, subtle plots, and fighting fate then just slaughtering millions. I don't plan on using any system for it, because all the players and major villains are around the same power level. As the world isn't finished yet, it may be a while.
Idea two-A western tale. Would follow more episodic plots and a few recurring characters than a massive arc story, but still fun. Different in that there are werewolves, demons, vampires, angels, ghosts, and some limited magic. And just like in the game doom, nightmarish beings can be killed. Some of you (butterball, Optix, Drisk) may recognize this as "Against the fall of night." Also may be a while, as I have school.
As a counter to "you all meet in an Inn", i'll probably be using one of the methods described at the below site.

It's also completely possible that I get someone else to do the GMing, and have it be a dual effort. I'd like 4-5 people before making any of them.
