I have high expectations for Creation Engine 2. Bethesda got a lot out of the original. I have no doubt that they've taken their time with Starfield and The Elder Scrolls 6 just to make sure this engine is ready for them.
As hyped as I am for Starfield, I can't help but think that it's basically a massive scale beta test for Elder Scrolls 6, just to make sure all the kinks are worked out before they release the successor to Skyrim.
