found this recommended to me on youtube. Sounds awesome yet kind of worry some given that it's multiplayer interactive (both competitive and cooperative). If BioWare were to ever do a sequel I would hope they incorporate a lot of what these guys are doing. The Combo creation system in general sounds like it might be a lot of fun, in that you can create them from scratch in a sense.
I'm most worried about the co-operative/competitive play, as I figure more people will be huge asses more so than cooperative players. Sorry BioWare your loss. 
our gain though. Power to the players.
