Bioshock 2?
FFXIII?
Prince of Persia 2008?
Underrated doesn't mean what you think it does, evidently, considering they were huge, triple A releases. :lol:
Underrated games are things like the STALKER series, Shenmue, Call of Cthulhu: Dark Corners of the Earth, Dungeon Keeper.
Hell, FFXIII was one of the biggest, most anticipated releases of 2010, but it sucked.
Now, with that out of the way, I'm pretty much gonna agree with Andy and say STALKER and Shenmue.
Of others, I'd say the Judge Dredd: Dread vs Death game, which kicked major ass.
The X series from Egosoft is also massively underrated considering the sheer scope, immensity and awesomeness of it, also, Fallout Tactics is the hugely under appreciated child of the Fallout series just because it did things a bit differently.
