Elite Dangerous is one of the most fulfilling grungy space sims I've ever played. I'm not much of one for the dog fighting side of things, but I do keep coming back to Elite to just do cargo runs or swap over to an Adder and push myself into the dark - scooping fuel off suns and try to avoid space hazards while just ogling the beautiful scenery.

It is a very strange "game" though, so I understand why it's not for everyone.
