What are Sony's "B Tier" games?

Maybe Resistance, Jak & Daxter, Littlebigplanet and Killzone, although they are arguably A tier.

Definitely Ratchet and Clank, Infamous, Sly Cooper and Wipeout though.

Certainly and I would put Resistance on that list as well.

Jak & Daxter is at this point neither A or B though.
