I think it's fine that the creator wanna make it a closed specie and get some profit of it but I think some are a bit too expensive.
I've brought I Madra, that is closed but it was rather cheap only 75points and a drawing (within an amount of days ofc or I wouldn't get the character or my points back) I think that was a very fair one.
I've also just brought a polette, that was a bit expensive and I even picked one of the cheap ones.
But I think it's a bit over the top when the creator want like over 1000 points for a character, I would never give so much.
And cool open species: The Rek Mesneh pg3 - Colors and Markings
, Porcuhound species guide
-I'm just curious, what where the cool open specie you've seen??
