I’d guess that companies that failed to turn profit when money was cheap are most likely doomed. However not all of the hype companies are like that. Some could be barely profitable, but shareholder pressure might push them to heavier monetization practices.
They are technically correct in that it’s the developers fault that they tied themselves to a proprietary game engine.
In the other hand Godot was nowhere near mature when the slay the spire devs most likely started development. They would be dumb if they used unity for their next game 🤷
