.NET object game alla Robocode

Hey there,

I just stumbled across Robocode, a java game by IBM where you program tanks to exterminate each other.

Now I believe there's also something like this for .NET, but I can't find it anymore and I've got some questions about it as well. I'm just starting to learn C++ and I already know the syntax but I have yet to write some real console programs. Then I have to learn VC++ (6.0) to start programming desktop programs. So I guess the question is, is C++ .NET totally different from VC++ 6.0? Cuz if I'll start trying to do the three mixed (ie, playing the game, learning VC++ 6.0 and ANSI C++) I'm afraid I'm gonna loose track. Also, can anyone point me to it?

Thanks :-)
