I stumbled upon Unity a couple days ago, and absolutely love it! I am a web application developer, but realtime 3D applications with physics are so much more fun than web pages! As a testament to the power of Unity, here is what I came up with on the first day I found Unity, including learning it... I have added some minor tweaks since then, but what you see was 85% done by the time I went to bed EDIT: Many different archived versions o Mars Explorer are available to play at http://MarsXPLR.com/view-268 Mars Explorer The vehicle is based off Forest Johnson's racer, with a custom paint job and significantly different physics settings. I am currently learning the Unity networking system, and hope to eventually have several different "teams" networked players will be able to join join - to all do battle on the martian terrain for the honor of their respective countries and monopoly of Mars' resources... Who can make it to the top of the volcano?
