Still considering my computer freezes if I build a park, I see no point to the expansion.
The Roller Coaster Tycoon series is on the verge of death in my opinion. It lost its magic back when WW was released, and ever since, the rest of the series hasn't captured my heart like RCT and RCT 2. They either have a lot of nothing (WW,TT), or nothing at all (RCT 3). Oh well, Atari will probally keep destroying the series until its beyond fixing.
