RollerCoaster Tycoon is one of the best Sim games to come out of the 90's. Created by Chris Sawyer it spawned a ton of sequels such as RollerCoaster Tycoon 2, 3, World as well as a 3D version and some releases on mobile and PC such as RollerCoaster Tycoon Classic which is a modern port of RollerCoaster Tycoon and it's sequel. Needless to say there are a lot of ways to play it and since I've been a longtime fan I've got my original RollerCoaster Tycoon and RollerCoaster Tycoon 2 on CD from back in the day. RollerCoaster Tycoon was available for digital download first on GOG and later came to Steam and I got the original deluxe version as part of a Humble Simulator...
