Can my toaster run this ?
Yes it can !
To run this game you’ll need Windows 95 or newer, a 90MHz CPU.
You’ll also need 1MB of video memory and 16MB of RAM, your toaster should run this game fine.
Play it in windowed mode
Since it’s an old game, I highly suggest you to play it in windowed mode. You might encounter some glitches when ALT-TABing or trying to click out of the window to do something with another app whithout having the click be registered.
The workaround is to right click RollerCoaster Tycoon title bar on the windows and then click out of the window.
Obviously ALT-TABing with your keyboard will work just fine.
