Rico was the first, CaptDESTINY was second, Sleepaholic was third, Kikko was fourth(?). Didn't know Elvis hit Lv 99
Right forgot about Rico, all he did was NHAA tho, but I remember Kikko hit 99 before the interface change, and Sleep was prolly third yeah
Rico did a lot of Team Demo, I remember playing against him and his friends. Kikko I remember seeing him around Lv 95 when OGPlanet got the badge/achievement system, which was after the UI Update.
