I played FlyFF, but it was too lame for me to go on to the higher levels, when you can actually fly.
Thing is, as for as I saw, you can fly there only by using a broom or a flying carpet. I'm talking about flying like Peter Pan :D
Since lots of people in Age of Time can finish all quests in about 15 minutes, including the Log challange, I think snake's idea is good. 20 hours of play time or even more will be required to fly.
