Then you have games that do space travel so well that I’m beyond scared shitless in them, like Outer Wilds. So many games have already managed to convey some of these feelings.
I think the big issue with a personal preference of realism vs. Fantasy is that Starfield has no commitment to realism in its execution (I say this with 12 hours played before I gave up). It is very much made to cater to lowest common denominator in other space travel things. The ship movement is very primitive and simplified. Travelling to new solar systems, landing on a planet, etc. Is done through fast travelling on the map to connect the different cells. It does not feel immersive in the slightest to me, and I have really enjoyed the “realism” of games like Elite Dangerous in the past.
Most damning is the lack of environmental planet differences. The only affect of a planets negative traits is suit protection reduction. There is no life support, your oxygen is just a stamina system. There is no vehicles. You are just running across barren, boring, procedural planets with none of the pomp and circumstance of games that have done effective space exploration.
Maybe in 2 years of mods you might have a more realistic experience out of starfield.
