Honestly though if blockland went F2p with microtransactions that would be fine.
Because I would loving pay for more faces and decals.
Because that loving stuff does not download serverside like prints can, nope. It's all client sided. Meaning custom faces/decals are basically loving worthless.
So all badspot has to do is drag and drop faces/decals into the add-ons folder, package it with the default game and sell it.
