Famously the Mega Crit studios, makers of Slay the Spire, have moved on from Unity. Following statement was released on Twitter with a hand wave emoji aimed at Unity:

  "The Mega Crit team has been hard at work these past 2+ years on a new game. But unlike with Slay the Spire, the engine we have been developing it in is Unity.

  The retroactive pricing structure of Runtime Fees is not only harmful in a myriad of ways to developers—especially indies--it is also a violation of trust. We believe Unity is fully aware of this, seeing as they have gone so far as to remove their TOS from GitHub.

  Despite the immense amount of time and effort our team has already poured into development on our new title, we will be migrating to a new engine unless the changes are completely reverted and TOS protections are put in place.

  We have never made a public statement before. That is how badly you fucked up."
