First python, then C#

My current plan is to finish learning python, and then learn C# for game development. Is this a good plan or should I bite the bullet and learn C++ instead? My plan isn't to do 3d games, more like Super Metroid, but can I randomize maps and such well with C#? I guess my question is, is C# a powerful enough language?

I'm not a Pythonista, but I don't see why wether someone plays a game or not would depend if he chooses one VM over another - it's mostly irrelevant (CPython being a bit slow would be the only major problem that I could think of).
