King Kong may be a Xbox port, but it's so good you'll want to relive the experience.
Graphics
Even the graphics for the Xbox were good, but the 360 makes use of next-gen power in this version. King Kong looks more like a battlehardened silverback gorilla, with scars and actual silver fur on his back. The textures are a lot more realistic and the characters look amazing...all except for Anne. She looks nothing like Naomi Watts in this version, however she did in the Xbox version.
Gameplay
Everything about the game is immersive. Limiting firepower and not making this game a FPS dinosaur hunt has a lot to do with the way the game plays out. You have to use skill and knowledge to get past some obstacle in the game, like fighting an invincible V-rex. Playing as King Kong is most rewarding, even more so because playing him in the game is rare, so when you finally DO get to play him, it's more of a gift than just another level.
Sound
Sound is also immersive, the roars of all the monsters and the little noise that the bugs make make you feel like you're on a lost island with big dinosaurs, giant bugs, and a giant ape.
Overall
This game may have a selective audience. If you loved the movie and love video games, then buy this. If you like the movie and love video games, rent it. If you don't fit the above categories, rent it. A lot of people don't like movie-to-game games or vise versa, so this is automatically for a select audience.
