Game Topic

After doing the "choosing on topic on wiki", I'm still undecided about my game topic. I have although narrowed it down to a few choices. However, I have no idea how to incorporate them into a game. Some of my ideas are: something to do with the body, like how blood flows through the heart or something, something to do with computers, like maybe identifying computer parts, or something to do with coal and jobs in this region. I chose action and shooter on the wiki because those are my favorite kind of games, I don't really think I could incorparte those into any of my ideas for the games. I was thinking more along the lines of a maze type thing, with pop up of facts or information.
