Re; Spycraft
I have been running the demo adventure for Spycraft, reviving my old Top Secret UNCLE campaign to do so, and the players enjoy it a lot. I think the mechanics (what I have seen, of course) are excellent. For this kind of genre, I prefer the mission team oriented nature of the classes to what was done in Shadowchasers, and presumably what was done in D20 Modern, although it's hard to judge since we haven't seen the finished product. I know I'll will be eagerly driving my FLGS nuts waiting for the Spycraft book and all it's supplements.
