Today I would simply like to provide a link to the outstanding work done by Jacob Poss on a FATE hack for Mage: The Ascension. He is taking the premise of Mage: The Ascension and really turning it into a FATE game that can stand on its own. You still can see the roots, but it has grown into its very own thing.
I like most of the ideas tossed around in the hack, even though I would probably do a couple of things differently when converting Mage into a FATE Hack. But then again, maybe not.
Also, I'd like to call out the faces Jacob puts on some of the posts. They are really evocative and reinforce the concept of the game.
