Gneech surprised us last night with an evening of a new version of the old D&D spinoff
Gamma World. Long story short, a post-apocalyptic world with its reality all tangled means that many people have odd and often unpredictable powers, some of these can change with little warning, and there's tech from ancient times, and stuff from the future too, just lying about. Character generation is also random, and rather amusing.
I ended up as a radioactive rat swarm with night vision goggles and a string of christmas tree lights.
The "everything is a power" mindset that makes 4th edition D&D feel like it's been ground up and molded into a poor tabletop world of warcraft clone works much better in this setting, probably mostly because there really aren't any classes, you just have whatever your randomly selected (at character creation) mutations/powers grant you, and an often-rotating assortment of temporary stuff and powers based on cards you draw. (these come with the game, and more can be bought, but aren't required)
I liked it.
I'm not alone in this, it seems.
