I think Unreal3 won't do the job, and that's because the team has so much experience working on Worldcraft that it'll be a shame to start all over, with an unreleased, unused new engine.
I also think they can't afford it
As for me, Sven really looks promising (we'll get to coop the sp!) and also Forsaken looks nice. I really want to see more SP mods, since a coop mod, a deathmatch mod and a teams mod will be all I need for the multiplayer part. I want content!!!
Rovient, you guys should look for another mapper, don't you think? I mean, you're all alone, that's gotta be tough Don't forget us when you're rich and famous
You too sig, your team looks like you mean business. All hail '87!
