An open-source reimplementation of the 1997 business simulation game Theme Hospital, with modern OS support and new features.
CorsixTH is a faithful open-source recreation of Bullfrog's 1997 business simulation game Theme Hospital, rebuilt from the ground up to run on modern operating systems. It preserves the original's humorous hospital management gameplay, including the full single-player campaign, while adding quality-of-life improvements like high-resolution support, unlimited saves, and custom content creation. The project solves the problem of playing a classic game on contemporary hardware and expands creative possibilities for players and modders.
This project is for gamers and retro gaming enthusiasts who want to play Theme Hospital on modern Windows, macOS, Linux, or BSD systems, as well as modders interested in creating custom levels, campaigns, and maps. It also welcomes developers familiar with Lua and C++ who want to contribute to open-source game reimplementation.
Developers and players choose CorsixTH because it offers a legally compliant way to experience Theme Hospital with enhanced compatibility, including native support for high resolutions and modern OS features, while maintaining faithful gameplay. Its unique selling point is combining exact recreation of the original with expanded capabilities like custom content creation, improved game logic, and full hotkey control, all as a community-driven open-source project.
