They Playonline account is free, Tetra Master is $1 a month.

Cid, I'm guessing you haven't played any MMORPG before. $13 - $14 a month is actually pretty good for a MMORPG. In fact, the only one I know of that's not worth the fee is Ragnarok Online, and that's only because it's still in Beta. Once it's actually done it'd probably worth the fee.
