Well, Jurassick plays privates regularly so just holler at him to play with the gamefaktions crowd. Just be sure to play on xbox, they usually shy away from pc players. I myself would be interested in putting together private matches with certain themes just for fun and for videos for the site. I would also set up regular more serious privates but people who join will have to play with both xbox and pc players. I would try to even the teams out as much as possible by having pc players evenly opposite of each other. I would also host all of my privates on a lag free dedicated server where noone will have host advantage, courtesy of JackSparrow. Only the future will tell.
Always remember, those who play Shadowrun are better than those who don't.
