It’s the same thing we saw with Halo CE Anniversary on the Xbox 360.
Edit:
you can downvote me all you want. That’s not how game engines work.
Just so we’re clear, that edit wasn’t there when I made this comment. Bro edited in a double-down even after getting real-world examples that are over thirteen years old. It takes a crazy kind of confidence to stare reality in the face and say, “Nah, I don’t like that, so it doesn’t exist.”
Halo CEA used the original Blam Engine as a backend and Sabre’s engine in the frontend, it just made the new rendering engine toggleable. Sonic Colors Ultimate did the same thing, too: the backend is the Hedgehog engine and the frontend is Godot.
This is good for indie devs, but don’t get it twisted, this is about attracting major publishers to the platform.
