Oblivion - just the scope of the world and the depth of the creation.
GTA IV - not my cup of tea as a game, but the city it creates really is a marvel
Uncharted - really nailed having a decent B movie and characters plus it had some great set pieces
Little Big Planet - I didn't think it would deliver on the promise of creation, which of course it did in spades - also for me the best art direction so far. I love the look and the graphics of this game above all others this gen so far.
Try to be reasonable... its easier than you think...
