There's actually an entire single player game on or parallel to the Star Citizen roadmap as well. "Squadron 42 Cinematic Teaser": https://www.youtube.com/watch?v=VppjX4to9s4
I backed this game just after it's kickstarter campaign 7 (?) years ago. Mainly for the MMO aspect.
The vision since has changed so much, I probably won't enjoy the MMO part. It looks more and more like a job in a space simulator, rather than a game that might not be 100% realistic, but at least fun.
Nowadays I'm just looking forward to Squadron 42, hoping they will at least manage to release episode 1 before running out of money
