i am trying to make a game for the 360 and i heard u need a license for that.If so how can i get one? Do i need 1 even if i dont sell the game?
This site is for Unity 3D You should go to Microsoft for this information. Maybe XNA. http://msdn.microsoft.com/en-us/aa937791.aspx
Try this forum thread.
To build for XBOX 360, you would need a license for Unity to even build out a valid XBOX 360 app. Before that however, you would need to get a license from Microsoft and to test you'd need a 360 dev kit. Then, you would have to contact Unity's sales department for licensing information.
