From the Square Enix E3 Live Blog:
Q: What influence have games like World of WarCraft have on the development of FFXIV?
A: As with WoW, we want to aim a bit for the casual user. However, we don't want to make a copy of WoW. We believe we will have things that are unique and will stand out from that game.
Thank goodness. Hopefully it will retain the unique qualities of FFXI without becoming a second job that *I* pay for.
I am a happy man right now.
