Further thought has me discounting TZ, etc. even more. Think how many of these wish lists were entered before a lot of more modern games even existed. That skews it terribly right off the bat.
I wonder how different that list would look if it only considered wish lists entered or edited within the last year (or something).
I see the site does record when a game is added to your wish list. So a date cutoff is possible. But a database query that counts all your wishes as long as one of them was entered in the past year is as close as we can get. Unless Robin has it saving old entries, marking them internally as removed with a removal date, then a query could also count all your entries if one was removed in the past year, to cover those that have removed entries but not added any. We would still lose those whose lists simply haven't changed in so long, but the result would still reflect reality better than "everyone still wants TZ, TAF, MM, ZZZZZZzzzzzzz....."
