How do you guys like the idea of achievement leaderboards? if 1, they change how achievements are accumulated - example, they can add achievements for killing a certain boss a certain number of times like 10/10 then there would be a achievement for the same thing but 20/20. The 10/10 would reset to 0/20 rolling over to a clean slate. Achievements for gold milestones - 'Has reached 1,000,000,000 Gold!'.
I would like to even see time sensitive achievements. For example, "Has earned 100,000g in 1 hour"
Some people will hate the idea I think, but people like me - those achievement seekers might like it - who knows.
