This isn't actually new and by now probably cheap as well so its just something Id recommend, pure fun and absolute madness.
Its basically about performing sabotage on a corrupt government and its military, the map is absolutely huge and you can just go around destroying shit however you fancy and/or advance through the story which isn't very long tbh but to reach 100% completed status takes a shitload of time (I'm at 40% after 36 hours of playtime ). I guess you could call it GTA but with a 100 times bigger map, planes as well as helis, lots of different environments (city, jungles, desert, snow mountains and water) and basically... just a much better game really...
