I GM Shadowrun (but I'm pretty new at it so I'm still trying to find the right balance between letting them succeed and throwing curveballs at them), and I alternate weeks with a guy that does BESM (in a setting of ... well, it's kind of hard to explain. Think a feudal city surrounded by land owned by corps that would make the most callous executive of a Shadowrun corp go, "Holy crap, guys. Going overboard much? Jeez..." with some sci-fi and fantasy elements thrown in and you've got something close to it. It's screwed-up, but in a good way).

Next week, I'm planning to try for significantly more hard-assed than I have been lately, and we'll see how it goes. XD
