If a game that sounds like a cross between Mad Max and Lord of the Rings sounds intriguing, you'll want to check out this massively multiplayer game. Up to 200 people in a single setting will duke it out in massive vehicles across a fantasy wasteland. Players take control of a huge vehicle and belong to a specific race, such as humans, evles, dwarves, etc.
Different races have drastically different vehicles with different characteristics.
The Elves, for example, have huge floating wooden sailing ships powered by magic. In the campaign mode, customizing your craft and picking up remnants of your fallen enemies is important. Though the game was only running in software mode, D3D support is planned. Force-feedback support is already working, however.
