hey
I'm going to college for game design.
one of the best languages and the one I'm studying in is c# it is used in unity and many other game engines but there are many more. Just to list a few c++, Java, and many more it is up to you. if you would like more info about this just let me know By the way what game are you planning to make that is one of the most important factors
Hope this helps
