At the main menu, click Tutorials button, now click the bottom
selection. (I cant remember the name). Now wait until the tutorial is at
the end, then click or press any key. You will have a roller coaster
ready built, but you cant buy the exact same one in the buy mode for
roller coasters (located in thrillers) You might have to practice
because after a few seconds, if you do not have control (for example,
the tutorial is running, but you didn't click or press a key) the screen
will return to the main menu.
