Sim Coaster PC

SimCoaster is a Strategy game, developed by Bullfrog Productions and published by EA Games, which was released in 2001.
SimCoaster (Also known as Them Park Inc and Theme Park Manager) is the third and last installment in the Theme Park series. It is a theme park simulator whose main innovation was that it allowed the management of several parks a the same time. In the game, the player must complete objectives, with the ultimate goal being becoming the President. 
One of the most renewing features in the game was the option to go into first person and walk around in the park, and being able to go into the rides. This however had many glitches like walking trough scenery and patrons.
