WotC doesn't want the flavor bleed. IIRC there were official articles on their website.If a remember right the very first issue of Dragon magazine after WotC bought TSR featured an article where the writer was talking about a M:tG-campaign-world for AD&D 2nd. Wonder what happened to that. He sounded very convinced it would get published. The Manastorm-thing seems to make more sense though.
I used 3E at the time. My players made standard characters from the PHB. They were hired by a wizard to recover an item that was lost when a trading caravan he owned was raided by goblins. He described the chest and the item (a large jewel) to them and said he would pay them in coin for whatever else they recovered on top of the jewel's recovery fee.I've seen "hey, how would you do M:tG as an RPG", a smattering of house rules, and a trailing off from the topic more times than I can remember.
Has anyone actually run a game set in the universe of M:tG? What system did you use? How did it go?
