I was disappointed that Crysis 2 would set in NYC because I love the tropical island setting much more than urban ones but it's not as barren as I thought. I'm very glad that there are a lot of trees and grass in the game.
Another thing I love about Crysis 2 setting is the vibrant palette. The gray/brown in so many games nowadays is an absolute turn off for me, no matter how great they are (i.e. Killzone 2, Gears ...).
