One of the major disappointments imo is that space isn't interesting. You only really go there for the odd ship battle to progress the plot or whatever, but you can't really fly between planets, so you miss out on the cool side stories you get with Elder Scrolls games by walking between cities. I was hoping for Firefly the Bethesda game, but it's just Skyrim stretched across planets that you fast travel between.
I want to find ships in distress, pirate outposts among asteroid fields, scuttled ships I can scavenge, etc. In other words, space should be a mechanic, not just a setting.
I think the planets are fine, but I'd rather have fewer, more densely populated planets. I don't think space-colonizing people would only make 3-4 settlements per planet, there would be dozens if not hundreds of settlements before moving to the next planet. I'd rather buy a DLC to get access to more systems then current setup where everything is spread out. In fact, just give me Sol with Earth, Mars, and maybe one of a Jupiter's moons being inhabited with the rest working like the planets in Starfield.
But no, it's just Skyrim set it space, with fast travel between cities. That's fine, just not particularly special. I may play it at some point, but it's not what I'm looking for right now.
