It *looks* amazing. Will wait for the reviews to find out if it actually is.
It's got very solid reviews.
Far Cry 4 review round-up: Ubisoft's sequel earns mountains of praise.CVG: 9/10 - "The strength of the world and its systems alone makes this one of the year's best games and one whose enormous potential for experimentation means you'll playing it well into 2015. By taking things to the Himalayas, Ubisoft Montreal has managed to skilfully weave an attractive partnership of awe-inspiring landscape and exhilarating, surprising action."
VideoGamer: 8/10 - "Far Cry 4 is a superb Skinner box, staving off monotony with constant upgrades, and it's so expertly crafted to appeal to baser instincts, so rewarding of you embracing them, that there's a strong chance you'll miss the broader point that all of what you're doing is utterly despotic."
The Guardian: 5/5 - "Far Cry 4 truly shines in the almost bacchanalian sense of freedom it bestows on the player as they traverse through its environment. In Kyrat you have the ability to go anywhere and do pretty much anything - much as Pagan Min would advocate. Here, the only pact you need keep is that with your conscience. God help you."
