Hidden Object Game--Choose Learning Topic

I chose my topic of Machu Picchu because I enjoy history, and I thought it would be interesting to make a game about it. It would give me an opportunity to learn more about the subject, and it might give the player some inspiration to learn more about it after having played the game. There are many things that I am interested in that I don't seem to have time to pursue but if it is a part of a project or work-related then I have to make time to do it. Those times don't seem like work at all because I enjoy what I am doing anyway.
