We've been featuring the open sourced version of RollerCoaster Tycoon 2 for some now, going as far back as when Indie Retro News was but a blip on the internet. But now fast forward to this month however, and thanks to a great heads up from one of our MS-DOS Gaming! members, we've been told OpenRCT2 has not only been updated to a final build of 0.2.6 but a new preview version has also been made available as version 0.2.6+.
