underated: Oddworld Strangers Wrath
overated: KOTOR

Most underrated:

Panzer Dragoon Orta
Chronicles Of Riddick
XIII
Beyond Good And Evil

Most overrated:

Grand Theft Auto (All versions)
Tony Hawk Games (All versions)

And KOTOR is an amazing game by the way....far from overrated....

KOTOR is quite good
KOTOR II was good until the lackluster ending

I would have to say Dead to Rights is the most underrated xbox game. It has an excellent storyline, decent graphics, and immersive gameplay. And the most overrated xbox game is definitely Metroid Prime.

lol did you just put metroid prime?

dude thats only for the gamecube

Mine would be:

Underated: Project Gothem Racing series and Fable

Overated: GTA series

...Metroid Prime?

Yeah, GTA and Tony Hawk can get old real quick.
XIII was definitely a solid shooter that did not get it's due.

I personally think the MechAssault games are a little overrated. I guess they're mainly for shooter fans who love very simple gameplay.

And stay away from Matrix: Path of Neo. Somehow it got some average reviews, but its just as bad, if not worse, than Enter the Matrix.

My eyes must decieve me, did you just say Metroid Prime?

Underrated:
Oddworld's Stranger's Wrath
Psychonauts
Phantom Dust
Ninja Gaiden

Overrated:
Halo: Combat Evolved
Halo 2

Ninja Gaiden underrated? That game got amazing reviews, and I haven't heard a single bad thing about it. If anything it could be overrated...although I wouldn't classify it as either.

Well, from what I was able to deduct, despite the great reviews, I haven't met many who have actually played it and the ones who have, complain about the difficulty and belittle it and hate it for that but the people in my community aren't people to really ask about games...

Underrated: (tie) Oddworld Strangers Wrath /Timesplitters series

Overrated: Madden 06 (The self-proclaimed best football game. It sure helps having a monopoly on an entire genre of games.)

Underated

Kameo for Xbox 360

the principle doesn't matter about this game, so what it looks like a naf cartoony style game but it is the strategie of the game that is required. Strategie such as Kameo are easily underated because of the style of game but the game can actually be easily addictive like with simulation games such as the Sims.

Most overated has to be the Grand Theft Auto games, although they look good it just takes one rather pointless mission to annoy you and also the story line behind most of the missions isn't even relavant to the main goals of the character.
