The predecessor to this game is FFXI, not XIII or the -2. The online games have very little to do with the single player games aside from a few rare character appearances and the combat system. And Chocobos
14 Came out in 2010 less than a year after 13 but before XIII-2. I always wished they had simply called it FF Online, and kept it out of the number order but oh well.
This isn't a new game, they are basically tweaking it to be a lot more like FFXI with the old Job System and stuff like that. I never played XIV (cuz the class/role system was so stupid) but I played XI for years.
Calling this gameplay is really a joke I will say. It's an MMO, there should be more than one player on the screen. That said though, the graphics are a huge improvement over XI and I don't know of any MMOs that look this good graphically.
The fact they had one perspective, no HUD, GUI, NPC/player names (or other players for that matter), and no fighting at all is disappointing. There are a few other videos that show a party fighting boss type battles though.
