What kind of game should a noob make for his first one?

Right now I’m just making tile sets for my first game. I’ve only been working in Java for almost a month now, and I wanted to try to make a game. So I joined this forum, and I wanted to see what you guys thought I should do. If you guys help me out with ideas, I’ll pick the most enticing one, and keep you updated with it’s progress. Thanks guys!
