Firstly, those looking for a sequel to the original Far Cry will not find it here, as it shares nothing apart from a slightly similar style of gameplay and it's name. Seems to been only called this for name recognition purposes only.
Aside from that gripe, the game on the whole is a pretty decent affair, though it won't be to everyone's taste. Graphics are excellent, with the environment nicely detailed and some great character animations. Sound is good, especially if hooked up to a proper surround setup.
The actual mechanics of the game work well, which allows you to play in a style that suits you, though a stealthy approach often works best. With a pretty decent selection of weapons, which you can only carry a limited amount of, allows for certain amount of tactical choice, and all the weapons can be upgraded to an extent.
There are also a small selection of vehicles (including boats) to chose from, which are essential for traversing the massive landscape, though only really one of them is particularly useful.
Where this game lacks however, is the bland story line and largely repeatative missions. It will take you a while to complete the main story, but towards the end I had become bored and just wanted the story to end. The finale was a bit dissapointing too.
