I don't expect anything like Star Citizen or any of the other games you talk about.There are four space games Im aware of where you pilot ships and get out on your feet, 1 has no gameplay beyond what I described, 1 is a tiny focussed puzzle game in effect, the others have boring mile wide, inch deep pointless gameplay.
None of the games closest to Elite has any real benefit to having space legs, and if you think FD can put together something even as "comprehensive" as Star Citizen you are fooling yourself.
Legs will neither fix the issues people have with the current gameplay in ships, and will introduce a whole threadnoughts worth of new criticism of the mile wide, inch deep kind.
Just come back to this thread if we do get space legs, i'll write it now:
TOLD YOU.
If the update is to be Elite Feet, it will be its own thing. I certainly don't expect to only be able to do the same thing from walking around with what you could in your ship.
If you expect Fdev to only do that, then I think you are wrong. There would be little to zero point in doing that and nobody would bother buying it. Nope, there are other ways elite feet can be added without treading on the toes of the main game. There doesn't even need to be "space station" gameplay to begin with.
