After Dori pointed me at a proposal for Advanced Squad Leader I took a closer look at area51.stackexchange.com
There are many proposals for sites based on games that I think can be (or already are) covered here just fine.
I opened a question to encourage folks to stop by and help us build a great site for all games. Please consider stopping by to assist. If you are an expert on any of the proposed games, it would be awesome if you could weigh in on those proposals as well.
