This is a remake of the Atari 2600 version of Boxing, produced by Activision. The gameplay is simplistic, but I find it quite enjoyable and challenging trying to knock the opponent out. It gets quite stressful when you only have seconds to go, and yet are trailing in points, which only adds to the enjoyment!
This was my first remake coded in 3D and was a good project to cut my 3D teeth on. It's fairly faithful to the original, but I think the 3D aspect makes it much more interesting. Unfortunately, this doesn't seem to work in Windows 7/Vista.
