I like the idea of real-time mana regeneration, which can be spent on spawning new adventurers, naming / transforming locations and creating items. When you create a character, location or item you are effectively contributing to worldbuilding. The history becomes detailed and a fusion of human and procedural generation. It it a bit like Twitch Plays Pokemon meets Microscope (the tabletop game).

Adventurers need a bio/tagline and a custom name. Locations items etc. are the same. You have to actually put some of yourself into it. Chris suggested Cortex Prime as a good source of inspiration.

I have lots of ideas that extend past that, but the idea of a evolving world that is slowly fleshed out by each player is very appealing.
