Not worth the time... Unless you speak Japanese and like farmers.
The language barrier is also huge. In off hours if you didn't speak japanese you were hard pressed to find a group. Coupled with the horrible in game translator unless you brought friends with you chances are you spent most of the time solo.
Soloing was extremely boring, and difficult as the game is quite hard. It was near impossible to travel long distances being there was no fast form of travel other then chocobo's which for some reason seemed to range in cost to use them.
Level progression was quite slow, and you'd spend most of the time killing the same looking npc's for hours hoping to level. When you got an item at level 10, it looked the same as an item at level 20. Everyone looked like carbon copies of each other.
Farmers, that is, people who sold items in game at outrageous prices so they could then sell the gold online was rampant. So bad that it pretty much ruined the game economies.
This game isn't worth the bother.
Graphics looked like PS2 quality, very grainy, with anime style.
Gameplay was lackluster, slow to progress, with little to no feel of advancement since you look the same as everyone else.
If you value being in the Final Fantasy World this is for you, if not stick to the single player games.
