Good approach, but highly overrated!

Criticism
1. you have to perform every single point of the tutorial also if and only if it appears otherwise not go further
2. the physics engine tends to zero ... at least you can not even cut down trees as it already is in Crysis. ie at the level of HL2 and not as in the Werd Bung: there is nothing that you can not destroy even the dispenser in the hotel lobby ... :-(
3. The starting point is always pretty much diagonally at the other end of the card.
4. when pirates Jeeps that have a degree overtaken as you 80 drove through the crap Dinger grade times only 60
5. over medium difficulty very stupid AI of enemies

Positive:
1. beautiful harmonious environment
2. beautiful graphics
3. can be played very well even with weaker hardware! (Eg Nvidia 7900GS at 1366x768)
