The cool thing about Far Cry 2 is you can play the game how you want. If you don't feel like undertaking a mission you can skip it and come back to it later. How you play it will also affect the outcome of the game, so choose your course wisely. Some things you should probably understand about Far Cry 2 before you get it is that the game map is massive! I'm not kidding, it will most likely take you up to an hour and a half to drive from the bottom of the map to the top and that is in a jeep. Another thing you will want to understand how to do is use a map.
