To put it simply this is is truely an amazing game. It may be short, but if you own a X-Box this is a must check out title. When I first read about it, the very idea of a Vin Diseal game made me laugh, Pitch Black was a horrible movie and to make a game around such a character seemed like a horrible idea. However, Riddick comes off as the next Tommy Vercetti, by the end of the game I couldnt help but enjoy his wild antics.
The first thing you will notice is the superb graphics. They are without a doubt the prettiest of any console game. My jaw dropped withing five minutes of first playing and stayed on the ground for hours to come.
The control layout is simple and easy to get acquainted with, I only had to check the control layout in the option menu once or twice before I had it all down pat.
The enemy AI is similar to Deus Ex, just dont do anything stupid and you should be fine.
The only flaw in the game is how short it is. I was able to beat it in about 4 days or so. Keep in mind I work 8 hours a day wich gave me about 4 in which to play the game, meaning you can probaly beat the entire game in one sitting if you really want.
In summary: If you own X-Box, rent this game, but its not long enough to bother buying.
