Thought i would put my two pennies worth in on this game since i have now been playing it non stop since it came out on the 26th. No wonder my wifes getting bored of me blowing the hell out of everything every day i get home from work! as previous reviews have said the graphics on the game are top notch - especially if you take a 747 up as far as the game will let you (about 5 kilometer which is bloody high for a game!)the world pans out below you as far as you can see and the real time weather systems / clouds, mist hovering around the game that can be seen from this vantage point are almost too real for a game. very impressve - then of course jumping out sky diving the distance or nose diving ino a building - or whatever! And there in lies the game. Its whatever you fancy doing realy. do a few missions, then wander the enviroment to find more villages / army bases to blow up for more points to unlock more mssions. or dont and spend a whole hour base jumping off the same mountain and die over and over again just to attempt to reach the bottom without getting killed! Or take a jet fighter for a spin through a few canyons at low level. people who dont like open ended sand box games shold avoid this becuase too be fair you cant get any bigger and open world than this game to date. the missions? fun but the usual stuff - blow this up, assasinate this person etc... but they are all fun as there is so many ways to aproach them. this game realy is all about the exploration of the enviroment the creaters have built and it works brilliantly. ive done 22 hours on this game, am not even close to boredom and i recon even a 100 hours wont complete all the villges 100%. Yes its got its downsides as others have commented but the pros outweigh.
conclusion: if you like your open world games and can make up your own adventure. buy this. but be warned, if you dont like these type of games you will get bored very quickly.
