But it's what makes their games unique. I'd hate to see them lose that by switching to a generic, widely used engine like unreal.
The outer worlds 2 already exists if you want a starfield-like game on a modern engine with fancy graphics. As does avowed if you want the same for skyrim.
The charm of Bethesda games (at least for me) has always been that they're these big sandbox games with huge levels of interactability and moddability. How almost every item has a physical presence with (albeit oftentimes janky) physics that can be toyed with and manipulated. That level of interactabilty is something you don't really see often in games these days. (Its something I really love about Larian games also)
It's always been what made a Bethesda game a bethesda game to me and I'm glad to see they're sticking with it. I just hope they're able to polish and further refine the creation engine without just blindly chasing better graphics. Graphical fidelity isn't everything.
I can't imagine a fallout game where I can't fill a bathtub full of old world money or an elder scrolls game where I can't fill an entire room with sweetrolls
