Guitar Hero, Crash Bandicoot, Tony Hawk, Call of Duty, Final Fantasy, old Nintendo franchises (Mario, Zelda, Metroid), any yearly sports series, etc.
Then theres games that are really close to becoming overdone (even though they still sell well) like Ratchet & Clank, Skate, Halo, GTA, etc.
I would have included Gran Turismo but they only come out every couple years usually and there hasn't been one yet this gen. There's been 3 Halo's and another coming 2010 so far this gen.
