Hell no!
I'm awaiting the sequal.
As much re-play as the original RCT and its expansion packs have... you can only milk a dry cow so far!
The game has gotten severely out dated. Sure, it is STILL on the top 5 selling PC games week in and week out, however... the sequal can be made very soon and much better & advanced.
Take a lesson from "Luna Moon Colony Simulator"... the game is from a similar viewpoint and involves building a colony on the moon, but it's fully 3D which means you can view it from any angle, zoom in & out with ease, and the graphics stay sharp even in the closest zoom.
If the next Rollercoaster Tycoon game uses that exact same engine (or a better build on it), you may not be able to ride the rides... but it'll look a whole lot more realistic than it does now, and surely bring you into the 21st century with the game!!!!
