Bioshock (when it first came out and it was only out on 360 and pc)...it also had a lot to do with the fact that 360 was getting a lot of ps titles as well such as re5, gta 4 etc (and that the ps3 was still pretty steeply priced at the time)...
Didn't really have anything to do with any of the franchises you listed and most of the stuff I like is multiplat anyway.
