Creston hit the nail on the head. Still, I'm sure it will be wildly successful, which is truly unfortunate.
As for an extra $1/month to prevent griefers... nice try! Look at how many people spend HOURS online tweaking their cheats or just being general assholes to other players. For $13 a month I can play FF. For $14 I can play FF and totally piss off a bunch of people. For any griefer out there, the extra 8% cost is nothing.
And YMS, storage space is not an issue here. Do the math. If each character is 100K (that is a LOT of data) and you had 400,000 subscribers, that's still only 40GB. Lets go nuts and say you had a MILLION subscribers. That's still only 100GB. In these days of 300GB IDE drives and SAN's, even 1TB is small potatoes. And it's not like FF will require more data per player than other MMO games.
Yeah, gamers are whiney, and they all think companies are trying to ream them. But in this case, they are right.
I'm so glad I gave up on FF and its ilk back in the SNES days!
