even before needing more players, the game needs more planets.
-Start by allowing players to have 2 planets and you double the universe size.
-Populate existing gals with bot planets.

I would go as far as allowing a player to own a full galaxy.
I can imagine for example a universe composed of:
- Private galaxies with 5 planets all owned by the same player + 5 bot planets
- Buddy galaxies with 6 planets owned by 3 buddies + 4 bot planets
- Random galaxies of 10 planets owned by 10 different players.
