Codename Alpha will (when finished) be a realtime strategy game (RTS), written entirely in Java.
For now, it is a Java RTS engine with a small testgame (including one kill-all mission).
AI uses an integrated trampoline-style cps-interpreter for scheme.
forty-two is a clone of the 1943 game written in C++. It is intended to provide a clean codebase for simple 2D shoot-em-up games using the SDL. Customization can be done by plugging in custom graphics, data files and scheme (guile) AI scripts.
