I do like Elite - graphically is quite good, save for all the beigeness and the godsawful default Orange color scheme (at least this can be edited), though it's still early in its growth and has a ways to go before it really starts to show its true potential. I'm OK with that though - it means I won't need to buy another game for a while.
I also like No Man's Sky. It's almost the opposite of Elite - the graphics are more graphic-novel, physics are simple, controls are simple, but it's some very impressive technology - the seamless transitions between docked at a space station to landed on a fully procedurally generated planet, terrain deformation, and scannable just about everything is, in its own right, pretty impressive, and it keeps getting better with each new update. Yes, there was a whole lot of boo-hoo at launch, because you couldn't find brand new players and shoot them every time they tried to move, and a whole lot of assumptions and expectations that turned out to be there, just very differently than was expected - and I don't care. I pre-ordered anyways and actually started playing Elite while I was waiting for the actual release of NMS. I formed my own opinion, based on my own experience, and I found out I happen to like what NMS has to offer. Only proves to me that the haternet isn't worth listening to in the first place - but I already knew that.
I'm also a huge fan of Mass Effect - from Mass Effect all the way through Andromeda - the story is great, and I even liked the original endings of ME:3, no matter who thought they weren't really endings...
And I'm really hoping to see a new torch passing a favorite old flame, and see a return to necromorphs and Markers with Dead Space 4.
Never been a big fan of any of the Star Wars games - even Battlefront 2 just doesn't do it for me.
I tried Alien: Isolation, but honestly I found it very dull and far too easy after blowing through it in just under 30 minutes.
The Halo series also never really did it for me either.
Unreal and Unreal 2 (the games, not UT) were certainly a good bit of fun.
Doom and Quake never did it for me either - they're just FPS variants, and that gets old for me.
Star Citizen looked like it was going to have a lot of potential, but their pay-to-win structure is such a put off, it's not even on my list of considerations.
I hated Eve from day 1.
I did enjoy the Wing Commander series, but it lacked replay potential.
For me, Elite and NMS pretty much cover the gamut of what I enjoy in space games - so I'll be sticking with these for the foreseeable future.
