Prius Online (Anima Online for old followers) is such a niche title that it will be near impossible for it to make Top 10 overall. It's currently #32 on the Gamemeca charts and shows a subscription ratio over the past 4 months like an insane rollercoaster. The unique playstyle and bad Item Shop (from what I hear) makes it tough as a steady title.
Aion is a good title to me. It's a mixture of Lineage 2 style looks and WoW quest driven gameplay plus a bit of it's own uniqueness in the setting, character customization, and overall feel. When the NA/EU beta hits I'd give it a try and see if you like it.
Yup, I've done the Top 10 KR updates for a few months now on a weekly basis.
