FF XIV was a snore fest. I don't know how it could attract any player base to be honest. The 'job' system is stupid (at least for crafting and gathering jobs) and the quest design was dumber and more plain than vanilla WoW when it started out. You had a quest of kill X or collect Y from Z for EVERY fucking single monster type in every location. That's about it. The main quest was also really uninspired and didn't took off. Admittedly, I didn't play long enough to get far, but the first few quest areas were sufficient enough to bore me away.Well... have you missed FF XIV?
If you are talking about FF XV. then you should know that it is basically FF VXIII and that was Nomura's baby, who wanted the whole "fantasy based on reality".
I am quite sure that with FF XVI, we might go back to seeing a diverse cast.
I actually like FF 15's approach and cast (at least the old one, not a fan of the new designs by any means). The setting sounds really intriguing and reminds me a lot of FF 7 and 8.
