Eclipse Phase. Several of the people who worked on Shadow Run also worked on EP.
I looked at EP, actually, when it was mentioned on these forums somewhere else. Honestly it looks really, really weird. The idea of being able to switch out your character's body and stuff pretty much blew my brain up. I'm not sure I'm ready for that level of sci-fi abstraction, you know? Even though they're just imaginary characters, their physical bodies are still a big part of their identities for me, to the point that I consider sketching the character an important part of character creation.
I've heard of GURPS, a bit, as I understand it, it's basically an all-purpose system that can be applied to just about any setting? Does it have any settings of it's own? I guess I should've specified, the world the game is set in and the way the characters fit in is much more important to me than how the rules actually work.
As for QAGS, not sure about that. To be honest, I prefer the type of game where the character running along your hypothetical catwalk would get ripped apart by gunfire. I suppose I can see the value of a game run in an action movie style, but usually I like meaner, more "realistic" games. perhaps I'll check it out.
Vattic brings up a similar quandary that I find myself in, actually. Having recently moved I find myself without a solid group to play with. I'm sure I'll be able to work something out, but have any of you played this sort of game over the net? I've seen games played through forum threads before, but that's a little too slow for me. I personally have GM'ed several shadowrun missions via an IRC channel and one over Ventrilo. Loses some of the fun of the dice roll and such, but it's still pretty fun. For the IRC version, I wrote out descriptions for some scenes before hand and I got to have my NPC characters speak "in character" without having to make a fool of myself.
Savage worlds sounds kind of interesting, though I'm wary of any system which has several settings like that. They often come out feeling half-finished to me. Do you have a link for it?
whew, think I covered all the bases.
