I felt similarly. Exploring is just another thing to “do” to get credits/nanites. It was cool to see genuinely new things like the huge Dune-styled worms but once you see one you’ve seen them all.
That extends to base building too. I have no reason to build a base anywhere else in the galaxy once I have a capital ship that does all my crafting for me. Except resource collecting, I guess. But meh, different strokes for different folks. I don’t think there’s been a non-MMO continually-updated game that I’ve come back to as often as NMS but coming back is usually pretty short-lived.
Hearing about this got me to reevaluate whether I needed Prime and I ended up cancelling altogether. Just a heads up, if you cancel mid-subscription (I was on the yearly plan) you get the option to cancel service immediately and refund what you didn’t use. I was supposed to re-up in May and ended up getting $63 refunded.
