I can imagine how troubling this has been being for companies developing your business over Steem network. Steem is a POC of what shouldn't be done on blockchain.

This remembers me of the early days of Joomla, when it was beta and many companies were founded to service extensions for it and helped on developing it, and when it was released its owners banned all extensions that weren't GPL, and so paid extensions became impossible.

Steem Monsters is by far the best blockchain game and I see no news of any under development game that would be anywhere as good. I humbly suggest you to, as a plan B, research how the game and its data could be ported to Waves, Cardano or Ethereum.
