I received original as a gift.  Great sound, gameplay, and fun.  Then when I installed this on it, gameplay wasn't that much enhanced. There no mode where its no worries about guests, ratings, or objectives, until you beat the game.  All it really did is add like 5 new rollercaoster, 2 trill rides, 2 shops, and 2 gentle rides (numbers may be off but thats an estimate).  and then it added around 30 new scenarios.  So its really a good game, but it could have added more themes and attractions.
