Daffy on 19 January 2009
Bioware owned IP of Mass effect, but most likely rights of first ME game were Microsoft, because they published it. After EA acquired Bioware, MS and EA did make agreement where EA did get publishing rights of first ME game to PC and MS did get...something.
It's more than likely that MS didn't want any money about those rights. Timed exclusivity maybe? Or maybe MS did did give rights of PC release to EA and pay some extra to EA to get full trilogy exclusive to XBox360/PC.
