The choice between Uncharted 2 and Modern Warfare 2 was a hard one for me. I've only played through U2 once, whereas I've put in nearly 100 hours on MW2 already. Both games have mastered their respective genres - no action-adventure game is nearly as fluid or exciting as U2, and no FPS has ever felt so responsive as MW2. Ultimately, though, I admire a well constructed narrative experience much moreso than a finely tuned online experience, so Uncharted 2 has to get it. It's pretty much perfect and had me on the edge of my seat the entire time. Whilst I enjoyed MW2's campaign mode a lot, it was in many ways a step back from what Infinity Ward achieved with the original game, and none of the aspects within it come close to the perfection Naughty Dog created.
TLDR; MW2 is my mistress I'll constantly go back to fuck, but U2 is the wife I'll love forever.
Also, for all my measly opinion is worth, I don't like the point system this year.
