Most fun I've had playing a PC game!
This game is a nearly perfect blend of action and adventure. It takes place mostly outdoors with expansive vistas (many games tend to have a very limited visual field, whether due to primarily interior or urban environments). It has many supporting characters with individualized personalities. The musical score is performed by the Moscow Philharmonic, and gives the game a "cinematic" feel. The interface was very easy to learn and uses a combination keyboard/mouse. This game is vast and will keep the player busy for many enjoyable hours.
I suppose the use of voxels to render the imagery was one thing that could be improved upon. There is a lack of rendered detail of objects. Oddly enough, this did not really detract from the game a bit. I have read that the sequel will not be using voxels and that the detail will be much better.
The Bottom Line
Outcast is a game to try if you are an adventure gamer and you need a break from hardcore puzzle solving. There are puzzles but they are so well integrated into the storyline, and they are usually solved within the context of the action. FPS/action gamers will probably find the action a bit tepid but this game is "aimed" more at the adventure gamers who like some action elements too. My wife and I both enjoyed this game very much!
