Unreal Engine almost has a monopoly at this point. It‘s also very friendly to use for small indie devs, not charging you anything for the first million dollars you make. Their license fees also seem rather fair as of now. But it doesn‘t help competition is flat lining left and right. Epic Games could feel their engine is worth a little more when Unity is gone too so I‘m happy to see many hobby devs give Godot a try first. I hope a company like Valve with their sheer infinite resources will see the shrinking market of Unreal alternatives and give their engine development a serious push. We really need more diversity when it comes to Engines.
