Replayability for Uncharted, Heavenly Sword and GRID

Hey guys,

I plan on getting another game besides MGS4 next month... Hehe... But I'm kinda strapped for cash, I so pretty much have to make sure that it's got uber replay value... Hehe... I plan on getting either GRID, Uncharted or Heavenly sword... Can anyone give me a lowdown on the unlockables and stuff for each one?

Thanks

Uncharted has alot (underline) ALOT of gun fights and its the closest to MGS4.
Don't forget, puzzles and platforms are just to pause the guns fights, to give the player the feeling that Drake is actualy trying to find something and not just senceless killing everything that moves like in some other TPS...

The colectables are not really hard to find, if you carefully you may find them all the 1st time you play.

Conclusion: Uncharted is worth for is amazing gun fights, A.I. and graphics these 3 are better than any other console game so far, specially gunfights and graphics.
