Something else to consider, LittleBig Planet and Motorstorm were both released before their developers were bought out, ergo both games technically shouldn't be up for consideration (though MS Pacific Rift and future games from MM and Evolution should be). Also, Halo 3 was actually completed before Bungie split from MGS, ergo it should be considered as part of Microsoft 1st party developed catalogue this gen.
