Ship interiors was something I always wanted in Elite Dangerous. It's my understanding that the ship designs were actually created with internal layouts in mind and that FDEV promised ship interiors at one point.
I left Elite Dangerous for a while when it became apparent that they simply weren't going to give us ship interiors. I played other non-space games instead because there really wasn't anything out there that fit what I was looking for.
I was excited about Starfield, waited for it, and played that for a while, but currently it's just junk. I have high hopes for it though and likely will return in a year or so when Bethsoft irons out most of the bugs and the modding community fixes all the things I hate about the game. I'll be honest, I see Elite Dangerous as kind of a relic. Still fun, but a relic.
Which is a shame because FDEV had a head start on all the competition and the game has so much potential with a bit of balancing, more ships, fixed interface, etc.
Elite CMDR here (exploration), if it matters, who has unlocked pretty much everything in the Bubble (with the exception of some Guardian weapons). Approaching combat Elite and I've got all the ships unlocked.
