I have played all of the single player FF games. I didnt play XI due to me primarily being a console gamer and the only MMO I had played during the time XI was released was Runescape and Runescape 2.

When I heard FFXIV was being released for PS3 I tried it out and fell in love with it from the FF aspect of it and the idea that I could create my own character look and appearance in a FF world, rather than the standalone titles where I just rename the main character.

The MMO and single player FF fanbase is slightly divided, but I think most of the people who play the MMO version play the stand alone titles as well and not the other way around.
