Well, I see one flaw with a downloadable file.
(But maybe that's just because I am territorial).
If you have a file with the name of every game in the list - complete with the status of the game (and maybe also a link) - then everyone could simply copy the list onto their own website.
All they would have to do is simply download the new file every month or so, and their list would be fairly accurate. Meanwhile - I am stuck with all the work.
