I stumbled upon a great wiki, Learning Can Be Fun, loaded with PowerPoint games that were already developed as well as a list of game templates for you to make your own. These games are great for reviewing material, reinforcement of concepts, or even as a pretest for concept introduction. Because this site is a wiki, all material is there for sharing. You are even encouraged to join the wiki and upload anything you create as well as being allowed to download all material located there. Your students will love the material found here, so do them a favor and take a peek!
