Great game - and a great GM / Gm-less tool!
I've not yet digested the system enough to use it (just skimmed through the PDF for the first time).
And still: its' brilliance shines through clearly.
Damn, I'd never EVER imagine a tabletop RPG system where not only the world, not only characters and events can be improvised on-the-fly... but RULES??
Wow! Deciding, say, the rules of magic half-way thru adventure - isn't it incredible? And whatever else may come up during adventures?
Which automatically means - we get an ideally customized ruleset while we play. Because it's we, the particular group of players, who choose the rules. The way we like them!
I love this Mythic!
