From there, you can grow, slowy but surely, until you're relatively close to another faction. At that point, you start rushing again, so that you surround the target, but only invade once. Deal with the counterstrikes quickly, then do a cloud break. Fill in the gaps, until they are utterly surrounded. At this point, they will probably surrender, but if not, simply make a dash for their capital. If you succeed, they will be severely weakened, and you can slowly pick them off, if they don't get recalled outright. From there, spread slowly, consolidating a massive power base. Make sure the outer border of planets is well defended. From there, go around the side of the galaxy slowly, until you encircle every other faction. From their, very slowly tighten the noose, making sure not to get to near to other factions. When a nation comes too close, strike for the capital, and repeat for their new one. With such a massive territory, you should be able to massively overpower them, and swiftly destroy them. From there, quickly began to conquer even more territory, until there is only you and a few other factions. Coming at them from all sides, use your large player-base to overwhelm them, crushing the last few factions mercilessly. At this point you will completely rule the entire map. The staff will then probably try and do something, but you bribe them to take no action. Finally, you shall rule the galaxy....
