All good things have an end.
I really hope Wube could make it more interesting to play in multiplayer, in games of 50 or 100 players, unfortunately there are no incentives for it.
I suggested to add some resources trading and currency, coupled with a land ownership system, to prevent trolls and scale the game so that any player can join, but it would probably require some balancing.
This game is already 10 years old and still going strong.
Unfortunately mods are not very good quality, or too difficult to enjoy.
Space age is interesting because new planets are being added by fans, but I don't think they're going to be as well designed and really bring anything interesting.
