They don’t want to. They have a formula, and the public and the market have spent decades saying that it’s good enough and want “Skyrim in Space”

If they want to change how inventory works they can, in whatever engine they are using. But why would they?

Also, I find pretty ironic to expect “Innovation” in a game with a number 6 attached to it, from a studio known for doing 3 franchises so similar to each other in gameplay and features that are used to describe each other. And to blame the tech for the lack of it.
