After he got Divorced following Return of the Jedi he raised his kids.
He raised his family and built up his properties.
I heard he wanted to make sure everything was stable before he went into making more of the SW films. They suck the life out of him when he does it. Watch the Episode 1 behind the scenes documentry. He tells the 2nd unit director that he will sit back and look miserable lol.
I look forward to him doing something else after Ep3.
