I thought it was the other way around. PS3 started out bad and people joked about "NO GAEMS, NO GAEMS" but then it got better as it got more exclusives (specially for people that enjoy Japanese games, there are dozens of Japanese-developed games that are available only in PS3 and they're even localized) and Microsoft seemed to stop caring about bringing new exclusives and the ones they still had started decreasing in quality (or even becoming multiplatform like Mass Effect). That's how I remember this generation. X360 even had good Japanese exclusives at first like Lost Odyssey, Dead Rising (which went multiplatform for the 2nd game and then exclusive again for the 3rd) and Infinite Undiscovery (which has the dubious award of having the dumbest title) along with the Halos and Gears. They seemed to stop caring about these and started to just focus on Forza, Halo and Gears.
