“OpenRCT2 is an open-source re-implementation of RollerCoaster Tycoon 2 (RCT2), expanding the game with new features, fixing bugs and raising game limits.”
A project I never see great brought up enough so here’s some love to a great classic game that’s been revitalized by fans.
OpenTTD and OpenRCT2 are two of the greatest things ever made. Highly recommended (not responsible for loss of productivity).
Don’t forget about FreeCiv!
