if you a fan of simulation like I , or just love rollercoaster you must own this , I have to buy all three indivisually , but you can pick up all three cheap , make sure you get this before rc2 so you can navigate through easily . there be a couple of drawback like any other game , like guest get lose will drive you nut , if you go build a ride for a few minute , you scare to return to you park and see it in a total mes. , the handyman be quite dumb , and the mechanic walk to slow when a ride brake down , that be pretty much it , a WARNING THOUGH : this game be very addicting I find myself play for hour and hour I think it be give I back probelem , bottom line buy the game .
