The first Uncharted, for its time spoke volumes, same with Ratchet & Clank ToD. That's 1 full year after the PS3 launched, a little late indeed, but not much when you consider the 360 only had Gears (as exclusive) and then had to wait for Gears 2 to get more of the same (no, Mass Effect and Halo 3 are not technically impressive).
Right now there are 3 games that are untoachable : MGS4 (2008) , Uncharted 2 (2009), God of War 3 (2010).
VERY Strong runner-ups: Killzone 2, Heavy Rain, Gran Turismo 5 Prologue (yes, it still amazes more than any other racer, technically).
I wish to add, none of those games are quite possible on multiple discs, perphas you could do it for MGS4 ("maybe"***?)... the others are just impossible.
