As a space simulator Elite runs rings around Star Citizen. No other game I know of comes even close. Frontier have modelled a 1:1 galaxy, 1:1 solar systems and implemented correct (as far as 2-body simulations go) orbital mechanics. I also prefer the "planes in space" flight model over "turrets in space", partly from personal preference (I've always been more a flight sim gamer than an FPS gamer), and partly from my superficial knowledge of biology - my understanding that people tolerate pitch G-forces much better than yaw (lateral) G-forces.Here's a question-
Is Star Citizen better than Elite? as a space simulator/game or do they have the same potential.

I played No Mans Sky when it came out. I think the release game was actually quite good, if you ignore the hype that no game could ever live up to. Since then I have re-started multiple times, usually playing for quite a few play sessions before dropping it (usually back to Elite). I've decided the reason is that while the early planet surface gameplay is quite good, the 'space' part of NMS is horrible. The planets are scaled, don't rotate, don't move, there's no orbital mechanics, the 'sun' is a skybox light source, the 'space' is full of asteroids, etc. It's not space at all, not for me anyway.
Star Citizen is between NMS and Elite. There's only one system, no orbital mechanics, the planets don't move, they do rotate, and the 'sun' is an actual object. Both the system and planets are scaled (differently!) and that just leaves me with that creepy not-quite-right feeling as I'm transitioning between space and planet surface.
For me, the potential of the games is the same. However, Frontier have built the better foundation. They've done 'space' right with few compromises, which is critical for a space game. They correctly (IMHO) decided that on-foot gameplay was important, but not critical. They're also happy to produce good-enough graphics and upgrade them later - I'm thinking about the planetary surface upgrades they've shown for Odyssey here.
I'm also much happier that Frontier is a successful business, with multiple successful games released. All the games help the business grow and support each other. I would be surprised if the technology and assets Frontier have developed for Jurassic World Evolution and Planet Zoo don't make their way onto Earth-like worlds on Elite, eventually.
