I just wanted to say thank yuo. I've been reading your stuff for a while, and just used your Vehicle house rules for comical and awesome effect this past week in my "Liches 'n B*tches" Gamma World game. (It's sort of a dark send off of gangsta rap videos, with necromancy.) Also love the energy weapon house rules.
Your stuff is awesome, and I'm planning to use a few more things as the game progresses. I shall let you know how it goes.
