RollerCoaster Tycoon World

On August 14, 2010, fans of the RollerCoaster Tycoon games were asked by Atari officials (through their forums) what they would like to see implemented in a fourth installment of the game. They also stated that they were "thinking hard about the next RollerCoaster Tycoon game on PC". Many fans assumed that this meant a fourth installment was in development. However, the only game that has been released since then was RollerCoaster Tycoon 3D for the Nintendo 3DS, while another release was announced for the iOS and Android mobile systems. Since Atari declared bankruptcy in January 2013, there is currently no official information on the fourth PC release of RollerCoaster Tycoon.

In 2013, RollerCoaster Tycoon 4 was supposively announced to be under development by Red Coin Games, with a trailer on Youtube. However, Red Coin Games has confirmed that this trailer is fake, no word on if the actual game is in Development. Though some claim to have heard rumors of Dreampark Studio to be made by Red Coin Games.

On 11th March 2014 RollerCoaster Tycoon 4 has apparently been teased by Atari on their Facebook and Twitter pages and it could be a mobile game because Atari had a post saying #RCT4M

A fourth installment in the series was announced on March 16th, 2014
