A lot of gacha lovers over there don't realize they are making efforts to get fishing and breedables banned
I personally very much doubt breedables will get outright banned. The new rules could mean
some of them might need to make changes to their primary product, but they will survive easily I think. So long as you know what the adult animal/fully grown thing you are buying at the time of purchase is going to look like, I don't think they will be affected.
However, if it's coat and it's eye colour or whatever other features it may have are random, then I do wonder if those could get caught by the gacha rules and may have to be changed, but I'd say that would be a fairly easy thing to do and it's doubtful, to me at least, that the creator's business model would be affected much by making that change.
There seems to be some talk about how paying for food to enable the breedable to breed might be seen as paying for randomised offspring which they think might fall foul of the rules, but that to me just sounds more like how they are marketed, and so long as the focus switches to buying food to keep the breedable you purchased alive I think they will be fine. At the end of the day, to me that seems more like just a kind of ongoing service activation charge, which isn't against any rules as far as I am aware.
As someone who doesn't do breedables though, I realise that there might be a whole economy built around trading the randomised breedable you got but didn't want that might be affected, particularly considering that Patch and the new FAQs seem to suggest that an item being transfer or not is significant, although I don't really understand as yet why that should make a difference.
