Which game sequels didn't fulfill your expectations this gen...

[Thechalkblock]

Killzone 2 - It was a good game, but not everything it was hyped up to be.
Resistance 2 - Also a good game, but I think they should not have changed the gameplay to be more Call of Duty-esque.
Halo 3 - Underwhelming sequel to a (once) great series.
