Aion would've fallen off the Steam and DIrect2Drive top ten sales charts, what with the fire hose blast of new PC releases. Fortunately for NCsoft, that isn't the case as the game is still clinging to said charts in the face of games like Dragon Age: Origins, Borderlands, Torchlight and Left 4 Dead 2. Boldness!
Actually, the game is pretty darn good -- if you don't mind your peanut butter with extra grind -- so that's not a huge surprise all things considered. It's always a good sign when an MMO can stay on the top ten after its launch, moreso when it does so against high profile, high pedigree releases. So, rejoice Aion players, you've likely got a strong community! (We could've just told you that, but now numbers vindicate said observation.)
