I did an IR for a couple that were in non-sports on my secondary account, but then noticed they aren't on the IR anymore and still in non-sport with no reply to my comment asking if they should be moved. I just assumed many weren't moved over when the gaming section was added. I would do IR's though but I don't have many gaming cards, only stuff from repacks and such and had to find them on non-sports.
As for movies or shows like Star Wars, I'm a bit conflicted on. I lean more towards moving them to gaming if they are actual gaming sets. I know there are wrestling sets the same way, and while it would seem obvious to keep it in wrestlng, some may only collect gaming cards and their first thought would be gaming. I think once the search function across all cards (not just by sport) becomes a thing on here, it will be easier to find things.
