Far Cry is a great new game, with a lot of bells and whistles that many of us are expecting to see in some of the other next generation games. The 3d engine is awe inspiring, with a draw distance of 1.2 Km (just under a mile).
The physics engine is also something to behold barrels with role down a slope realistically, and float in water.
The only real draw back to purchasing the game is the system requirements, recommended is a 2 GHz processor and 512 Mb of ram. If and when you go out and by the game, I feel that you'll be even more excited about some of the games we are expecting to see in the near future!
