I first played this game when I was 7 or 8 on the SEGA Genesis. The DS versions a delight with some great new features!
I only rated this a 10 for my classic love of the game as a child. I personally find this to be superb on the DS with the touch screen. The game has 3 difficulties which allows players to move up after getting more accustomed to things, though I think i prefer staying on the middle difficulty so that you dont lose all the work you put into your park. Its still a great game with very little(IF ANY)problems, meaning you should never be FRUSTATED by playing this game. Its pure enjoyment for those who understand the SIM based genre of games or if your not the hardcore gamer you should fit right in.
