Roller Coaster Tycoon 2 is an old classic Business Strategy game which flows surprisingly well and is very cheap.

User Rating: 7.5 | RollerCoaster Tycoon 2 PC
Not only are you able to design your own coasters and trade them online with other tycoons, but you’re essentially asked to build an amusement park economy from the ground up. People who know enough to put bathrooms next to their more nauseating rides won’t have to rely on their handymen to clean up as much puke on the paths. It’s the simple, yet strategic, portions of this game that make it a blast to play. Savvy owners will watch their parks burst at the seams with customers, while gaming morons will look at their deserted grounds and wonder where they went wrong. On the flip side, when you’re trying to place a coaster, it can be unbelievably difficult to see where you need to build a path so your park-goers can enter it. That, a few other technical glitches, and the title’s graphical ineptitude hold it back, but they in no way hinder RCT 2 from being a solid buy
