"Firstly, compared to auto battle, this battle system has more room for customization and strategy. Commands are personally chosen by the player. In FFXI, because of the jobs, partying was a necessity. Depending on the circumstance in FFXIV, I can either go solo or join a small party."
"Right now, the game is made so it is possible to solo"

"While FFXI has changed over time, it's still party based," Tanaka adds. "For FFXIV, if you want to play solo you can. If you want to play in a party you can. If you want to jump in play for 40 minutes or for long sessions you can. We'll offer different play styles for many different people."
