I played one game 20 years ago. This game about amusement park:you should building park with various objects and carousels. As they are created, appear park visitors. But I don't remember titles of this game. Who played it?
You're almost certainly talking about Theme Park (http://www.mobygames.com/game/theme-park) right? Unfortunately, I never played it myself or any other simulation game aside from the original Sim City.
It looks like this is exactly this game
