You can also search for geeklists, although the interface is a bit clumsy. First, you probably want to check the "titles only" box, unless you are searching for an obscure word. Second, you need to know that it is a whole-word search, so for example searching for "micro" wouldn't help you here. And you have to check all the forms of your word, so "microgame" and "microgames" would be advised.
Maybe that's why I didn't find it when I originally searched. Thanks Kevin!
