Shame, can you imagine seeing a busy station for once.
I play in open, it feels very solo.
Shame
have you done the numbers of players and how many stations there are in the bubble? huge play area, to few players means for the most part, an empty play area.
We have roughly 20 000 inhabited systems in the bubble, that is some 20 000 instances of super cruise....
We have ~166 000 stations, outposts, ground bases etc within 500 LY of SOL-system... That is 166 000 more possible instances for a player to be...
Then we have all the conflict zones, Signal sources, resource extraction sites. creating even more instances...
And this not counting all the other instances created when you interdict a ship, drop randomly in rings etc. etc
So no, going open only will not fix your desire to make the game less "empty" of players... you would need ALOT of more players. and for that to happen, the game needs to provide much more enjoyment to an even larger audience, and most of those potential players are not interested in PvP, so that has to be dealt with. and if we remove the two strongest options players have to avoid PvP, ie removing Group and solo mode, then we are looking at some drastic changes to the core mechanics of how the game works...
So, there is no lack of imagination about what could be if this imaginary thing happened, as there have been several occurrences where we have seen what you seek. and it is interesting to note that the biggest player driven event in the game, was done by explorers!
Community Goals tend to have busy stations too, and once again, two reasons for players to avoid open on Community Goals. PvP and no desire to sit and wait for a landing spot open up, with no working landing queue, just hammering away on that request to land over and over... and many who visits a community goal, do so to participate in reaching the goal instead of just hanging around.
But take any backwater system and ytou are most likely going to find yourself alone there.. and no matter how many suggestions to force players into open will fix that.. to few players to large play area...
