A Rollercoaster Tycoon game for Nintendo 3DS is in development.
It is being made by n-Space, the developer of the DS version of Call of Duty: Modern Warfare 3, and published by Atari for a March 2012 release.
Rollercoaster Tycoon is described in the latest issue of Nintendo Power magazine (reported by Go Nintendo) as an all new game in the simulation series built from the ground-up for 3DS.
It features full 3D graphics, new design options and new pre-built rides. And there are, of course, touchscreen controls.
