Aviation is a flight simulator meant to be somewhere in between accurate but complicated simulators and simple toy simulators that don't provide any level of realism. It currently features a non-linear flight model, a configurable atmosphere and sky model, and a CLOD triangulation engine for the terrain. Currently Aviation allows you to fly around in an area of around 600 square kilometers centered around the Columbia river. It can be easily extended to implement combat or air race scenarios, for example.
Billiards is a cue sports simulator. It aims for physical accuracy and simplicity. It should be useful for practicing billiards on your own and against your friends when a real pool table is not available. Both a pool table and a billiards table (that is, with and without pockets) are implemented, allowing you to play eightball, nineball, and carom billiards games.
Bitfighter is a game that feels a little like Asteroids on steroids. It's a multiplayer space-based combat and strategy game, featuring customized ships, multiple game modes, cool retro graphics, and smooth network play. It also includes a full featured level editor, Lua scriptable bots, and other cool features. It has a very active development team, so the game keeps improving.
The Cafu Engine is an all-purpose, modern 3D graphics engine and game development kit. It is feature complete to get you started quickly. It can be used to create a variety of 3D applications, including games, simulations, and training and architectural software. Written in C++, the tools, libraries, and framework have been designed to make the development of new games and other 3D applications easy. 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.
