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?

OP, if you aren't doing anything too math or resource heavy, like 3D gaming, then C# should be fine, and would probably be much easier than C++.
Like >>8 said, C++ is a little more machine efficient. It would force you to learn a few more concepts though, like manipulating pointers and memory management.

While I love C++, I really think  you'd be better off with C#.
