I'm late to the piece as the game came out a little while back now. But I've just started playing it! I've played 3 and if I'm honest, it's much the same. FC4 is just a lot bigger. The basic premise of the game is the same as well. Random guy is left in the forest of an exotic place and must find his way home with the help of the native people. Some want him dead, some want him alive. Why? Who knows, but that's how it goes in the Far Cry Series. I do love the game play though, the crafting is great fun, the harvesting of plants for power ups is great, and the open world mechanics of everything is a 8\10 ! Just give it a go before you buy it, in case you don;t like it in the end lol
