Wow, this is a serious throw-back. All i have left is some old gamma world modules and notes listing a few dragon magazine gamma world articles. It was a cool setting i thought, if a bit cheesy on the equipment side. Post-apocalyptic settings are ok, they do not hold a lot of appeal for me (though i enjoyed Cyberpunk a lot - i live in Seattle, lots of local references). The setting is actually really cool - a blend of fantasy and sci-fi. Mutants, AI all sort of cool things you would expect. The entire world has not really been totally built out - leaving GM's a lot of room to fill in the balnks. The games we ran in that world were very cheesy, but looking back the setting seems like it would be a really fun world to drop players into. Not being a big fan 3+ DnD and the D20 system overall, i know the've brought it up to date, but i'm not sure the results.
