OpenSA is a downloadable mod for Windows, macOS and Linux that recreates Swarm Assault, a 1999 real-time strategy game. Players control swarms of ants, beetles, spiders, scorpions or wasps, with no resources or population cap; the original campaign was recreated and multiplayer over LAN and online is included. It uses OpenRA as the game engine and supports any resolution.
The Peacock Project is a replacement for HITMAN's servers that runs locally on the user's machine. It is described as fast and easy to set up, requiring ownership of the game, and features monthly custom content.
CorsixTH is an open source project that re-implements the game engine of Theme Hospital and loads the original game data files. It aims to serve as a base for extensions and improvements to the original game. Playing requires the demo or the full Theme Hospital game.
OpenRCT2 is an open source re-implementation of RollerCoaster Tycoon 2. The site offers a download of the latest release and an OpenLauncher, plus a getting started guide, user manual, FAQ, Discord and Reddit support channels.
Interlude is a free-to-play keyboard rhythm game built for fun, currently in open beta with latest release 0.7.28.6.

It includes in-game downloads for songs and noteskins, plus an Endless mode system.
Clone Hero is a cross-platform rhythm game based on classic instrument controllers. It is playable with 5 or 6 fret guitar controllers, midi drum kits, game controllers and keyboards.
