Make no mistake about it, this is a great game. The only slight problem that I have with it are the graphics. I'm not saying they're not fantastic, they are great. There is however a lot of slowdown, especially in the city. There is also a lot of jumping in the grapics. I have not worked out whether this is the game at fault, or whether the TV I have is not up to scratch to play it, even though it plays other PlayStation games fine.
Other that that this game is likely to give you many a days pleasure, and is about 5 times longer than the previous one, not to mention having great replay value. One of the first missions involves scaling a crumbling tower to capture a flag, and it was so much fun. This lets you know very early on what the quality of the game is gonna be. :)
