Elite has 100x the content and playability of star citizen and is probably thousands of times less buggy. They're not even comparable.

I downloaded star citizen out of curiosity during free fly last year and there's virtually nothing to do. That's if you can even get into your ship without crashing. It took me many attempts. Core gameplay loops just aren't there. The only people having fun are those that "make their own game" by role playing.

I've played a good amount of Elite. I got bored eventually but there's a ton of solid gameplay and virtually no bugs. It's a better game than star citizen in its current state in every way I can think of.

The buggyness of star citizen is unforgivable. I've played many early access and alpha games and nothing I've touched is as unplayably buggy as SC has been for years.
