"Biggest drop in quality" sequels

[Veknoid_Outcast]

I think Jak II represented a noticeable drop in quality from its predecessor. Not a bad game by any means, but just not as great as the first installment.

I would say Perfect Dark Zero, but there's a GBC game in between it and Perfect Dark for N64.

Edit: I forget Duke Nukem Forever. I think that one takes the prize.
