The most disappointing video game sequels?

[Pemalite]

Master of Orion 2 was a classic and one of the greatest games of all time, follow by that POS thing called Master Of Orion 3.
Most of you probably don't know the game, it was released in an era of gaming where developers weren't afraid to gamble and release something completely different and new.

My next one has to be Perfect Dark: Zero. Merely a shadow of it's former original self that was on the Nintendo 64.
