In Pictures: 15 Hot Games You'll Be Playing During the Holidays

Crytek's spiritual sequel to Far Cry, Crysis is a tale of anti-grav aliens wreaking climatological havoc off the coast of the Spratly Islands in the South China Sea. The game is shaping up to have shrewd, tactically aware artificial intelligence and absolutely stunning graphics, possibly the best we've seen on a PC. Since everything in Crysis is fully destructible, battles can dynamically reconfigure an environment (rocks shatter, buildings collapse, trees topple, crates burst apart), but the enemy fully understands its relationship with those changing objects, allowing it to adjust realistically in terms of using cover and reacting tactically as battlefields transform.
