It would be a bit much to claim this is a 'master' or 'authoritative' list, but it offers perhaps a better way to look for things than the 'games list' at the website.
The language filtering in particular does not work well. This has been a "spare time" project for a few years now, but I never get around to preparing it for general consumption.
It was your website that basically brought up my mostly-in-jest-to-stir-the-pot post.
I've been using your list as my "master list" for some time now, the organization is great, the list of variants is great. I recently got a "lot" from eBay that included many duplicates, including quite a few Canadian, and a few international, variants, so your site has been a blessing to figure out exactly where they were each from.
