Is there any way to make different accounts on Roller Coaster Tycoon?

u mean so if someone else, or "another account: went on, they wouldn't have all the completions that you have on your "account"? I don't think there is. It doesn't really matter though, because you can just save the parks with different names (ex. Diamoned Heights, Diamoned Heights1), and then you can play as many as you want...
