What do you think of a C # course?

All codecademy courses are focused on web development, I’m not complaining, I’m currently learning javascript. But I would like a C # course that comes from codecademy, since it is the next language I want to learn. Also, C # is one of the most important languages ​​currently so it would be very beneficial for this hypothetical course.
So I ask them: would you like a C # course? But what other language would you like in a course?

That would be good because I want to try to start a game company with one of my irl friends
