The Brickadia people are totally insane. They seem motivated entirely by spite from BLF drama that happened almost 20 years ago. They've been in early access for like a decade because they have no idea what they're doing. Despite wanting to make "Blockland but betterer" I am pretty sure they still don't have mod support outside of letting you load custom scenarios and prefabs, which are pre-approved on their website.
They aren't serious about making a successor to BL and they're permanently tainted with the reputation of "that blockland ripoff with constant pedophile discord drama."
