I really had fun with this game. I would say it is similar to grand theft auto and assassins creed. The end if the game is a bummer as they don't make it complex, they just throw cops at you and that means you just end up running from them. The general concern that hacking / stealth is not rewarded as you can usually just run and gun through a task is valid. But to be honest, had they fixed that I think they would have just thrown cops at you and the cops are the worst part of the game
I'll try to keep this short. The story could have been better. A lot better. Some times it gets a little ridiculous. The graphics were less impressive than expected (Except the water graphics, it's the best I've ever seen in a game). Too many of the same puzzles within the game, they just get annoying after the first 50 of them you do. I had a few frame rate issues when a lot was happening on the screen. Overall, it's a good game to mess round with for a while, but I wouldn't recommend buying it.
ps. There is a bit of female nudity which is always nice in a game.
