I got all the Aeons and my important stuff by 60 hours. I still have yet to finish Tidus', Lulu's, and Kimahri's Celestial Weapons, but the other 200 hours were just trying to perfect my characters, My luck level is at 90 so far (NA version), HP at 50k, and stats at 255. I have played it 4 more times through with 20 hours each. Monster hunting took an hour for me, defeating the creations also took 3 hours total.
