Originally it had the ability to play as crafting or gathering as a main. And would have had the company system (enhanced linkshells/guilds), the ability to craft in groups, etc. But since Yoshi-P took over many of the creative things that would have made the game stand on its own have been removed.
I mean honestly, what will this game compete on? In almost every aspect it can't even hold up against FFXI pre-abyssea.
And please don't assume I'm trying to be negative or say this game will fail. I'm just curious what all the people who believe this game will be really successful think about this.
Personally I think this game stands out in the graphics department + in the music department. Other than that, I haven't read of anything that sounds overly unique coming anytime soon.
