It's not like I'm against the idea, as I'd enjoy the game regardless. But I definitely don't think that the game needs it. It needs it for a certain type of player, perhaps.
I played the game back in 1984. And even though I'm not into modern social media (eg facebooks etc), back then my neigbour and I used to put our PC next to one another MSX and C64 version to get a feel of multiplay together. This is what's happening now and it's great.
Tbh every feature added is a richness for someone in the community, hence for the game in general.
It's more a question of priorities (due to limited resources). Right now they're adding chained missions (much requested by many) and planetary landings (very immersive). FD tries to find balance in releasing content. We should all await "our turn" and maybe sometime (indeed maybe in years) the OP will get the outpost building.
For me personally I would like to have group-list (much like friends list) showing all players in green on hud (like wingmembers in blue). Would be very practical and make game less annoying for me, without in any way bothering someone else (unless misantropes who want to pester me
But there's so much still to add in the game!
Just never say never, but be patient. Rome wasn't built in a day.
