OK, take a delivery mission from the crowded space station you're currently on, load a rover onto your ship (by which I mean actually load a rover onto your ship, not just press "equip rover" in a menu) . Walk onto your ship (again, meaning actually walk onto your ship, not just load straight into the cockpit), travel to your fly down onto the planets surface without a single loading screen, head down to your rover bay, get in and drive over to the delivery location to deliver the package. All without one single loading screen at any point in the process.

The closest I can think of to that is space engineers, except space engineers doesn't really have "missions" in the same way SC does and the station would be a ghost town, and all the ships/rovers would look like LEGOs lol

Don't get me wrong, the game is very unfinished and even by alpha standards it isn't at all perfect and there's a 50/50 chance that at some point in the process above you'll get a 30k or some other game breaking bug, but I don't see how you can have played the game like you say and not think that it's doing things other games aren't. There's no other game that I'm currently aware of that actually provides the same immersive experience (when it works) as SC.

Whether or not those extra bits of immersion actually matter to you is an entirely separate question, but they are present and a good measure further than any other scifi game I'm aware of. If I'm wrong pleasepleaseplease fill me in, because I fucking love that shit in SC but can't deal with the bugginess for more than short intervals lol

More people need to try Starsector. It’s so goddamn good.

Are you saying you played it in 2015 and your whole opinion is based on that experience?
