Coaster

Coaster is one of the first roller coaster simulation games. Published by Disney Software, and including (in the full, non-demo version) some of their well-known coasters, this game allows players to design and ride their own coaster designs. It provides an easy-to-use visual editor, and a decently rendered 3D view when you ride your creation. It seems like that's pretty much it though, there's no simulation aspect, you just build and ride coasters, with a panel of judges or something which rates your creations. So not much "game" here, more like a neat coaster building toy.
