There are virtually NO if any games that allow multiplayer across platforms.
No MAJOR releases (correct me if I'm wrong but I might be wrong about 1 or 2 titles)
was considering getting it for Wii U, until EA released trilogy on ps3 and 360 for lower price than you can get ME 3 for Wii U.
There was Shadowrun on the 360 and PC. I only played the demo though.
I remember that. It was a fucking load of shit, not a Shadowrun game.
