Glest is a free 3D real-time cross-platform fully customisable computer game. The game is set in a period reminiscent of the Middle Ages and contains two playable and customisable factions, Magic and Tech. Since the release of version 2.0 there have been many changes, including new units, upgrades, and an overall expansion of the game. Version 3.0 added online play over LAN/Internet. In addition, new features are continually added with Glest Advanced Engine, or GAE, a completely separate engine that is also cross-platform. GAE is upwardly compatible with Glest. Glest has a fairly large community, with custom maps, units, factions, and tech trees. Excellent graphics and gameplay! Glest is Cross Platform.
