Rifts/Palladium is the straightest, most purely male-focused role-playing game on the market. Equipment lists over social abilities, in fact no social rules at all, that's one thing. But they also have the annual swimsuit edition, which is consistantly the "femme fatales" of their game world. Last year, I think, as a joke, they did illos of all the pudgy white male game designers on their staff. I wonder--not that it's important or even relevant--if they have any gay NPCs. A lot of game systems throw in one just to show they're open-minded.
