Lots of Fun, Great Graphics !
first off the graphics are excellent, with a good pc you can run it on high with no lag and a map full of buildings, cars and people. you can get a insane zoom with the camera to the point you can watch people entering and exiting buildings and going about there day.
i will say the difficulty on this game is hard, once you get past the first couple missions things start to get very easy, this isnt something a kid could pick up and play easily, you need to have some form of knowledge on trade and economics or you just wont make it very far. some islands are easy to get a cash flow going, others you need to balance your imports and exports properly or you risk losing lots of money, very fast.
the missions are generally straighforward and usually involve putting up some different buildings, whether it be an airport, trade building etc.
once you get a good handle on it you can be making exports that are selling upwards of 200 grand every couple months, and the more ports you have the more frequent your exports.
all in all it is a very fun game, it has a "god mode" which basically restacks your cash every month to 500 grand, this mode is extremely fun because you can essentially do what you want, when you want.
if you are a fan of city builders i would say try this game ! ! !
