Good game in general. Visually excellent.
AI of enemies seems much improved.
However, a lot of the gameplay detail that made previous far cry games more immersive than most FPS games isn't there anymore. There's little in the way of animation when you're interacting with the environment.
Sort of a two steps forward one step back feel to it.
Oh and no hang gliders or paragliders which sucks.
Worth buying but wait till the price drops.
