When NCsoft released Aion, they had hopes it would ultimately enjoy the caliber of success in western markets that the title has in Asia. It's been roughly one month since Aion launched in North America but it's off to a good start, as indicated by its entry to the NPD Group's September US PC sales chart at number one.
Aion usurped competing titles like World of Warcraft and Champions Online in the NPD rankings, and the Aion Collectors Edition took the number five slot on the chart as well. Not bad at all for a game that only launched in the third week of September.
