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?

It's just less supported, you'll often need to roll your own X, for some values of X. Not a big problem for most everyday programming needs, but for others (like targeting an architecture not supported by your compiler) may be harder. The compiler may provide some tools to help you.
Also, the haters are annoying.
