Q3Rally

Most open source racing games seem to be realistic simulators. Or atleast on that side of the field. Q3Rally, on the other hand, is as arcade as it can get. It's described as both a driving game and a car combat game, and there appears to be a lot of cars and tracks to choose from - with more available on the project page. Q3Rally has been quiet for quite a long time, but seems to be getting a revival currently. Bookmark if you want to keep track of it - I did!

I found no full screen, so this cropped image will have to do. The car and shadows sure look nice though.
