Far Cry 2 is what you might call a risky move. In a culture of playing it safe with first person shooters, Ubisoft Montreal has created a title where you have to essentially make your own fun. It gives you all the tools you need, but at the end of the day you'll only get out of Far Cry 2 what you want. If you go in and treat it like some generic shooter in a giant map, that's what you're going to get.
If you fly in on a hang glider under the cover of night and play the game like it's actually you in the wartorn African country, your experience will be entirely different. GameArena strongly recommends the hang glider option, and they strongly recommend you pick up Far Cry 2.
