The good ones, meaning the original and RCT2. They're back! RollerCoaster Tycoon Classic on the App Store, amazingly optimized for touch control. Includes all scenarios, ride types, etc from RCT1 and RCT2.
Six bucks, no micro transactions. The two RCT2 theme packs can be bought within the game, and for another six bucks you can get Toolkit, which is RCT2's ride designer environment, scenario editor, and the ability to import and export files via email, INCLUDING RCT2 parks and scenarios from PC for those like me that still have their files!
It's like the best port to mobile ever IMO
