UniKnowledge 2 is very similar to the last UniKnowledge. The concept is the same: develop a sample game project and document the development. You can comment the code, create a tutorial, record videos and video-tutorials... it's up to you. The best entry wins, and by best entry we mean the entry that teaches most. However, UniKnowledge 2 has a theme. The sample game must be a vehicle-oriented game, meaning that you can teach people how to make a good kart racing game, or a dogfight game, or a motocross game... etc.
How it works
This contest consists of, basically, building an easy-to-understand and well-documented sample game project for Unity users. You don't need to worry about media, you can just use primitives and/or prototype media. The important thing is that you finish the game prototype and teach well: from brainstorming, to game logic and programming. The objective here is to develop the best sample project, not the best game.
http://forum.unity3d.com/viewtopic.php?t=37533&postdays=0&postorder=asc&start=0There's a contest in the Unity community for a sample/tutorial project for a vehicle based game. They have some prizes, such as Cheetah3D and Modo licenses. Now that Unity is free, it should be fairly easy for anyone to take a shot at this.
