7 so I could have a chance at boning tifa, and since I know so much about shinra after playing (how to sneak in, escape etc) I could join soldier and help them boost security -- mainly it would be locks over the air ducts. I would also point out all of the rebel hideouts that the ff7 team used which would help me work my way up to a very high rank. For retirement from Soldier I would requesition cloud's villa and open up the "Sunny Bee" in costa del sol and spend the rest of my days working on my tan and flexing my pecks at beach babes.

Scratch that, 11 so I could bone mithras.
