Originally I wanted to hold off buying this because I thought I might not like it (at least not $60 worth of like). Now I may hold off buying this because I fear I might like it TOO MUCH. I worry it might interfere with real-life obligations (I am weak - I'll choose to play a very fun game over doing important chores and projects if the game is addictive enough). Maybe I can make this my own personal carrot / reward for checking off all these obligations from my list. "When you finish XYZ, then you can buy and play Starfield!"
As I tell my family, when it comes to dieting, I win that war at the grocery store, not in the kitchen. If something yummy makes it into my cupboard, then the battle is already lost!
When it comes to Starfield, the only term that comes to mind is
bewitching. It's an odd feeling. It sort of reminds me of Elite Dangerous during its first year: the game annoys with its various shortfalls, but there is already enough there to keep you coming back for more, sort of like a sexy witch with a wart on her nose. For example, when I play it, I often find myself wanting to go back to X4 because SF lacks that large-scale enterprise feeling. So, I close the game with the intention of returning to X4 later, but when I do come back to my PC, it's right back to Starfield! I keep asking myself why I am so hooked on this game, and I still don't have an answer.

But it has sunk its claws deep into me. Again, I think it is because I see the vast potential that it has, not just with mods but with updates and DLC from Bethesda. As with Elite, Bethesda has built a rock-solid foundation that has the potential to expand in all sorts of interesting ways. And Bethesda's commitment to the long-term development of the game just makes me all the more excited for its future.
I know you said you weren't interested in Game Pass, but I would say for $10, it is worth a spin just to see if you will be entranced by it as much as we poor Spacelord Randalls have been.
Update on my adventure. I decided to try a mission board-generated survey mission. It was to Tau Ceti III. When I arrived in orbit, my scan found a science outpost. I approached the place with caution but was pleased to discover that it was just a bunch of scientists conducting research to see if the world could be terraformed. With the exception of a brief quest to place some sensors around some gas fumaroles, there was no other drama to be had, which was a nice break from the action. Even the mission board outside the station was empty. (Was this a bug? Or are missions generated according to need, as in X4? If the latter, that would be really cool! I need to know the answer to this!)
After that brief encounter, I set about surveying the planet. It was a very bleak world—cold, windy, and with a dusty atmosphere. It took some doing, including exploring a cave to find all the elements I needed to scan, but I got it done. The last thing I found was the planet's unique feature: pools of liquid metal with crystals growing out of them:
I then decided to do some poking around and came across another settlement, this time of would-be colonists making a hardscrabble existence from the tough terrain. Again, no drama or gunfights, which was nice. Just people doing their thing. I took a moment to sit with them in their prefab while the wind howled outside (there is some GREAT sound design in this game!):
After resting a bit, I headed back to my ship and decided, just for the heck of it, to land on the other side of the planet and do some further exploring. Upon setting down, I saw this tower in the far distance (also great draw distances in this game!):
It really intrigued me, so I decided to see if I could walk all that way without hitting a wall. VASCO and I set out, crossing the rocky terrain (more praise: you can tell the artists over at BGS examined the photos from Mars and Titan to get the rocky landscapes looking realistic. SF beats Elite's terrain gen by a mile!).
After covering about 1.5 KM or so, I could see the tower getting closer and larger:
It seemed to be on a hill. March on! (Yes, it was here I wished we had an SRV. I fully expect one to arrive with a future DLC.)
Another 1 KM or so, and we made it! It turns out it was a radio transmitter station. It was guarded by some rogue robots. When I finally made it inside the station, the computer logs indicated that there was some sort of malfunction or user error on the part of the staff that set the bots to "eliminate the useless humans" mode.
And that was my adventure last night! I did a survey mission and did some random exploring for about 90-minutes of gameplay. WARNING: This game is a huge time sink, but in the best way possible. Not a grind but just too much to do and see! I think I've only done three mainline quest missions so far and haven't even moved beyond the starting city of New Atlantis!
