Fully enjoying Starfield on Xbox. I've not played it yet on Windows, but will after the DLSS support is in general release (out of beta), so looking forward to that.
Starfield is so deep and complex in a good way, I find that the more I play it, the more I like it. There are so many different things to do, unless you only like one or two of them, I don't see how you could get bored with Starfield. When one activity starts to feel repetitive, do something else. Repeat. You'll eventually get back to the first one, but with so many mechanics, by then so much play time will have passed that it feels fresh again.
There have been a fair number of negative reviews. I don't think they're all from PS fans -- some are sincere. I agree that a buggy for driving around planets and the ability to walk or fly w/o NEEDING to fast travel everywhere would be nice (especially in New Atlantis -- if there's a way to get from the landing area to the upper city without using a fast travel loading screen, I don't know it, and that's clearly something you should be able to walk w/o taking the train). But those are hardly game-breaking problems. They're UI annoyances, like inventory management in every game (I don't think any games do inventory management well).
