I'm a long time rpg player and fledgling gm. I've spent most of my time in the d20 fantasy arena (seems hard to get away from it) but got into the Mutants and Masterminds system as soon as it came out (great system btw). I've dabbled into Shadowrun in the past but my current gaming group are hardcore d20 guys. I'm dying to either run or play a good, gritty, sci-fi game but I can't decide what system to use. I purchased the new Serenity sourcebook and it just doesn't have the depth that other sci-fi games do (i.e. Shadowrun).
I've read some of the reviews of Shadowrun v4 and it appears that they have streamlined some of the rules (not sure if that is good or bad). I also love the downtrodden cyberpunk theme too.
With that said, do you guys recommend SRv4 for fairly new players or is there another solid system to run? Or is that a stupid question to post on a SR board <grin>?
