That learning how to program comment is important because this course doesn't assume you have any previous programming experience. Don't worry if you've never written code before; we'll start at the very beginning and work our way up to building a small, complete game by the end of the course. Throughout the course you'll learn core programming concepts that apply to lots of programming languages, including C#, and you'll also learn how to apply those concepts when you develop games: drawing all the entities in the game world, updating the game world based on user input and simple physics, playing music and sound effects in your games, and so on.
Computer programming is really fun in general, and programming games is even better!
Caution: Beginning (assuming no prior programming knowledge) is not the same as easy (not hard to do). Learning to program IS hard to do, especially since this course is essentially a freshman-level college course. Meeting the course challenges while you master the material will be rewarding to you, but doing that will require hard work and maybe even a few expletives along the way.
