When I qualified in Computer Science – game programming was not even an option for students. Over the years though it has become front and centre for courses to have an element of the development of games and the principles required to write these games.
However all is not lost if you want to dip your toes into the world of games programming. Game Maker by Yo Yo games is a development tool that allows you to develop your own games. Theres even a lite version which you can download free to get started. You’ll find it here.
Good luck and good gaming.
