killzone 2/3 - i'd rather see it completely rebooted though. shadow fall wasn't nearly as good.

resistance - mostly resistance 3 which was by far the best of the series. another i'd prefer to be rebooted though - i'd personally give insomniac another shot at it. i know R3 was the least successful commercially, but critically it scored very well indeed.

motorstorm - don't tend to like racers in general, but pacific rift and apocalypse were a bit of a blast.

MAG - another i'd prefer to see an actual sequel than a remake/remaster. it had a lot of potential that zipper didn't quite pull off. whether it was too much of a technical challenge for PS3 i don't know. it just really needs to have the shooting mechanics tightened up, and the visuals modernised.

or as somebody else suggested.. a best of vita collection, which has killzone mercenary, uncharted: golden abyss, unit 13..
