Actually if this could be closed. I decided I am just going to continue with C++, if I regret it in the future then I will deal with it then.

If you're looking to do games in C# I say just jump in. If you have even a marginal background in C++ (which it seems like you do) you'll have no problem understanding C#. Start here, there's a lot of tutorials and code samples to look through. Get a few of those working and if you're not satisfied with your understanding of the language I've never had any complaints about the O'Reilly series of books.
