What lesson could you code at an ok level for games in C#?

Answer 1

My take on this is: Want to code games? code games.
Stuck? Learn enough C# to get through. Then code games again. Stuck again? Learn more C#.

The emphasis is on coding games, which is your primary goal. Learn enough practical C# to understand what you're doing. You don't need to be an expert.

This way you would keep your focus and interest level and achieve your goal.

You can dive into the deep end later if you want.

Answer 2

Do you mean how good should you be to code decent games in c#?
You can use game engines to help you and that can remove some of the work for you, but you should still have a solid foundation of the language and principles of programming. Knowing how to comment your code, write it so it's easy to understand/read and reuse, and how to inspect/troubleshoot code.
