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. It also states that they are "thinking hard about the next RollerCoaster Tycoon Game on PC". Many fans assume that this means a 4th installment is in progress.
