It’s a tongue-poke at Star Citizen
Genuinely though, nobody has published a VR/classic title at MMO-scale with PvP FPS, which is the ballpark that ED is in (going by their proposals).
There are a ton of challenges there. (Game design and balance for varied input formats, locomotion, UI display, item interaction etc. Plus performance concerns on the VR end. It’s a lot more than it sounds.)
NMS is getting there, but weighted much more towards PvE in low population instances, AFAIK. Payday 2 is 4 player co-op PvE in small maps. (They’re both cool

. And great proofs that ‘crossplay’ works with VR, but shy of the above challenges).
The only straight up PvP I know of is in Rec Room, but it’s in small arena maps. (I believe there is much griping about balancing

. But it seems to work pretty well from what I’ve tried).
Most other crossover titles are again small player count PvEs in the main, IE The Forest etc.
If ED hits all of its goals for Legs (EVA, station based PvP etc), and retains something close to 32 player instancing, it’ll be breaking some ground. (Not that all of that will definitely happen in the next DLC)
And PS I haven’t mentioned the vehicles

. (The odds of ED needing a virtual joystick interface etc, ideally better than NMS’s version to match the flight complexity, is high to me. Seems the only way to pull off a ‘AAA’ transition between legs + vehicles. So... one more thing for the complexity list...

)
TLDR: ED would likely be breaking some new ground if they introduced Legs with reasonable VR support.
