People, we're already here. Yes, the game doesn't support a lot of people in one instance, but we're here promoting our factions, working together, puzzling out the background sim and unleashing froggy vengence on anyone who shoots one of our tadpoles.
Fortunately both the Galaxy and the bubble are large, so if you don't want to interact with people or have their activities affect your gameplay you can find a bit of the bubble that no-one else is in and play there with your mates and not have to worry about big wings flying around. If we ever get the option to fly our flags in game (honestly, I want ship naming first) no-one says you have to join or make one. You can continue to fly solo.
