This October, Wizards of the Coast is releasing a "D&D Genre Setting" boxed set for Gamma World, using the 4e system. Oh, and there will be booster packs of randomized Mutation and Tech cards.
Let the wailing and gnashing of teeth begin!
But hey, it's nice to see the boxed set making its long-delayed comeback, right? And between these boxed sets and the impending release of Dark Sun, it sure looks like WotC is trying hard to win over fans of the TSR era.
(Honestly, I'm not sure what to make of this announcement. On the one hand, if you were ever going to make a game with randomized player abilities on cards, Gamma World would be the one with which to do it. I will admit it appeals to my love of randomness. On the other hand, I have never been a fan of "booster packs". I also wonder how, and if, this card-based character generation would integrate with the D&D Insider online tools.)
