It's a good simulation with lots of variety including an extra movie making feature! Definately Worth buying!
The only concrete criticism of the game is that in order to enjoy all of the goodies in sandbox mode you must play the game and unlock them first. However after playing the game for a couple of hours, it quickly grows on you as well as give you a chance to learn the controls.
Overall, the game is a good buy especially for those who enjoy simulation games . Plus the extra movie making feature gives it a creative edge and greatly increases the replay value.
Definately Worth buying!
