This one really makes me think...
But,this is what comes to mind.
PC: ONI
Horrilbe graphics,no story,Awful voice acting.
X-box:Halo by far...So overrated it's ridiculous.BORING.
PS1: Prince of persia/spawn
PS2: Obscure(i forget the rest of the title)
PS3: The re-boot of the prince of persia games/White knight chronicles
I agree with Oni, it actually looked pretty good going by the cover and back of the case, but playing the game it was absolutely awful, I'm glad I was only borrowing the game from a mate and didn't buy it.
