Hi, imagine you've become Galactic Emperor or Empress of the Star Wars galaxy and first Galactic Empire at it's zenit of influence and now you have to think about what to do with all this power. I'd have fun with commanding all those Stardestroyers and TIE fighters. Adrian the Cool
Reform and improve everything. Sure it might take millennia to do that, but why not get the project started.
End the war against the rebellion by signing a peace treaty. Make peace with the Jedi. Get Lando& Han to help out design the best casino in the galaxy. Take Jaina as my wife.
I'd get rid of most of the senate, then i'd declare that everyone had to give me all their chocolate so i could feed it to the Ewoks
I'd send a team of anthropologists to see where the heck Yoda and Yaddle came from, and I'd stay away from little kids from desert planets who could one day throw me to my death when i'm torturing his future son.
