They are actively and continuously developed in order to provide the latest technology.
CorsixTH is a clone of Theme Hospital. As computers evolve, we risk losing some classic games. Bullfrog's Theme Hospital, published in 1997, is a classic simulation game, but getting it to run natively on modern operating systems is getting progressively harder. CorsixTH aims to reimplement the game engine of Theme Hospital, and to be able to load the original game data files. This means that you will need a purchased copy of Theme Hospital, or a copy of the demo, in order to use CorsixTH. After most of the original engine has been reimplemented, the project will serve as a base from which extensions to the original game can be made.
The Crate Game Engine is a game engine that is designed to make creating games trivial. The rendering and scripting engines are removed from the game engine to make the specialization of games as easy as possible. Currently, scripting support is implemented to allow a Lua script to be put directly in the game file, which can be validated as XML. Multiplayer text based adventure-style games can be played with the existing console rendering engine.
EGSL is a small interpreter which can execute Lua scripts. It includes some functions for fast and easy game development. These are image manipulation functions, functions for 2D drawing, sound and music, input via mouse, keyboard, and joypad, and some helper functions. The engine is based on SDL, SDL_gfx, and SDL_mixer, and additionally on SDL_image on Haiku-OS.
