@Theresa: I feel the same when it comes to Ryniak minis O:).
I think it’s only too much when people stop buying. That’s the clearest sign people have had enough. I’ve never been a fan of these pieces, but did notice all the different variants. With toys I do collect that have a lot of variants I usually stick to the colours I like. I used to be a completionist, but I’ve stopped with that because it’s just not possible to collect every single piece (plus I don’t want 15 colourways of the same toy).
