What I hope to do in Globaloria

In Globaloria, I hope to gain more knowledge about computer gaming and how to make a game. I've never created a computer game so I am hoping that when I complete this class, I will have the knowledge needed to make one. I want to make a math related game with the theme of West Virginia or Marshall. I am most excited about making a game, but I am scared that I am not going to know how to make one and get lost along the way.
