I think this is an excellent idea. And yes it has been done on other sites and such and in other boards. However a place to flesh out combat and grand events would be nice, and as a more combat oriented character I’d gladly put some time into it. However I think there should be some rules set in place. Such as they have healers etc that actually prevent the fatality of your character after a match. After all, when people invest all that time into a character, they don’t want to see it gone within’ a couple posts. I know I’d be displeased knowing I just got my heart pierced by a spear, and then munched on by war dogs. Poof, character and all time invested gone. /wrists
As for rewards. I’d go along the lines of stat rewards and just the satisfaction of being able to RP a dream battle against a certain character or hated nemesis. Or perhaps if describing combat is your thing, and you find you detail it well, it could be a place to test your might against a myriad of opponents and monsters. Events such as; can this man survive the onslaught of ten crazed prisoners with clubs! Place you bets!
All in all, great idea. Needs to be fleshed out more, and needs more positive reinforcement.
