Rifts is a kind of nostalgic guilty pleasure for me. I'd probably call myself experienced -- I used to play it a lot -- but extraordinarily rusty. But, if you guys get something together and want to go shoot some lasers, I'd be game. @Mizore: power armor/mecha are a huge part of Rifts. There are conversion rules for Robotech characters, although it might end up being pretty janky. But, if what you're going for is "person with cool mech" Rifts has you covered 19 different ways.
