I started 07 with my only goal being getting 200m Agility. I halted that to try to become the first player to max instead. I was the first to 99 Agility which meant that I'd inevitably gain additional post-99 Agility Xp from Fishing and Runecrafting. I did about 800k past 99 at first and then obtained over time an additional 1.3m+ Xp from the above mentioned skills. You really, really like Agility!
