Oh by the way, I also made a Wiki for
Gamma World. Its is for all edition of Gamma World, and Metamorphosis Alpha. Unlike the MF wiki, this is going to be about official content - like how the Smurfs Wiki notes all the characters based on the cartoon, and notes some background trivia about them. There is only me and a guy who have yet to edit. it needs love - A LOT OF IT!
So far I have thrown 1st & 2nd GW text as placeholder text. I have made two nice pages - with cool pics - for armor, but its too stat-heavy. What I'm hoping to do is make the text stat-free fluff, and then add big fancy templates for the stats, that a condense by /hide tags. That is, its a block with:
Gamma World StatsFirst Edition [show]Second Edition [show]Third Edition [show]Forth Edition [show]Alternity [show]d20 System [show]Metamorphosis Alpha StatsFirst Edition [show]Second Edition [show]Third Edition [show]Forth Edition [show](lets avoid the 4e vision - not to rule it out, but to avoid those annoying C&D orders, as the game is still publish and supported - but we can still make note about the fluff)
By clicking on [show], the full stats are displayed. There will be stat templates for creatures, robots, items and mutations. I have been dragging my feet on this, do to a lack of information.

As for your Exaltated conversions, go ahead and start a page about it. As for your Angels, Demons and Devils, Biblical Apocalypse and Magical Awakenings are well within the scope of apocalyptic scenarios (as noted in
Gaming Philosophy - which is full of great ideas).
