So you want to rule a planet/nation?
Sure, you could get the darned Dragon Balls. Heck, you could take a planet by force! Have the GS vote you in? Pshhhawww.
This guide will walk you through purchasing a planet and starting your empire.
Go to Uberia, to the Real Estate Office, and post about you arriving there. A staffer will roleplay the Official Real Estate Doofus.
He'll ask you what planet you want, the name, the features. If it's a planet that exists in our world (ie Mars), then you can forgo the descriptions. The man will give you an amount of money you should pay.
Pay it, biyatch. Now you have a planet.
