I can confirm that the RCT2 Expansion Pack scenarios are impossible to complete or win. I tried completing them, but I ultimately give up. There’s no point of playing them if you cannot finish them.
The setup may be nice, but the setup is also why the scenarios are broken. I wanted to get all of them completed, but if they weren’t so broken, I would’ve completed them all.
Just to give you guys a heads up. If you’re going to play RCT Classic or RCT2, don’t even try the Wacky Worlds or Time Twister scenarios. Just stick to the 95 main scenarios RCT Classic provides.
