It's a good idea. The only problem I can possibly see is the game might not be able to handle so many different base types... I'm probably wrong but I mean, there are so many factions. Even if only the main ones get their own bases, that's still a hell of a lot of new stuff. Then are we gonna want individual tradelanes and jump gates next? Where do we draw the line?
I'd be happy with the jellies getting their own bases. But I'm pretty content with the bases the way they are right now. But maybe it's just cause all the Rogue bases are asteroids, except the ones in Cassini which are pretty extravagant.
