Is there a monthly fee?

ya 15 monthly

Pretty much like WoW.
You need to buy the time card

I have another question... when you buy the game does it come with 1 month free or something, or do you have to buy the timecard as well?

It comes with one month (free)
But you have to either subscribe with a credit card or a game card, if you subscribe with a credit card, the amount of money will not be charged before the month is ended
