Shadowrun 2007 ...
Don't kill me, I never played the original games (on the list if I ever see them) but I loved the hell out of this game on the 360. Now I know its basically defunct because its online only but I saw this game at Half-Priced Books a few weeks ago for the PC and I bought it instantly. This game is just a lot of fun and a really cool concept that was under utilized but so much fun.
