if so how much a month?

How are you this clueless and have a good chunk of fg?
You probably should consider not reproducing because the time you took out of your day to ask us here could've been better spent asking google, or even your own damn common sense for the answer.

Just because he has fg doesn't mean he'll know much about Aion, you idiot.

@op, Aion is still pay to play on retail servers, but in february EU is going F2P with major limitations on free accounts that really are game breaking.
If you're determined to play for free though alot of people here seem to play IA (infinite aion) a nice server which is pretty well updated =o

So many words and so angry. Yes / No would have sufficed.
