OpenRCT2 is a free and open source recreation of RollerCoaster Tycoon 2 (RCT2), also incorporating some features from the original RollerCoaster Tycoon (RCT1) that RCT2 removed, while also fixing some issues in the official game. In addition this, it also adds a lot of features, such as cooperative multiplayer, that allows several players to co-build a single park.

Development of OpenRCT2 was started on 2 April 2014 by Ted 'IntelOrca' John, with the project making steady development progress due to the efforts of other volunteers contributing towards its development. In order to keep the game playable and testing easier, OpenRCT2 called into the original RCT2.EXE for functions it didn't yet have itself, replacing these functions bit by bit with its own code. On 15 October 2015, this process was finished, making the game independent (except for graphics, sounds and objects) and easier to port to other systems.

OpenRCT2 is available for Windows (Vista and higher), macOS, Linux, FreeBSD and OpenBSD.

There are two branches of OpenRCT2: "develop", which is updated up to multiple times a day, and "release", which is updated every few months. Generally, it is recommend to use develop. If it has an error, it is likely solved shortly afterwards. The launcher can be used to keep the game up to date easily. The link to the download page can be found at the bottom of this article.

Comparison with RCT1 and RCT2

OpenRCT2 aims to continue where RCT2 left off, making it an update to RCT2 in a similar way RCT2 acted as one to RCT1, or how Loopy Landscapes acted as one towards the original RCT1. Most information on this wiki about RCT2 directly applies to OpenRCT2 as well, unless otherwise noted.

Since it currently still used the same save format as RCT2, it means that some limits are still in place. Examples are:

  • 255 rides and shop/stalls in a park
  • 1,000 guests in a queue line

A new object and save format is planned, which should enable the project to eliminate these limits, and to bolster support for importing RCT1 and RCTC saves.
