Considering FLYFF or Fly For Fun is a free game, If you have enough patience, your getting on ok game, with a strong community that is willing to help even the neediest of MMO players out there.
Its an MMORPG that has around 6 islands, wich are fun enough to explore the first time. But after that, the only reason you keep going back to them, is the people you met in the game. They are friendly, and most of the time helpful.
The quests in the game arent all that exciting. They all involve something like killing monsters for an item they drop, killing one specific monster, and stuff like that.
Not the greatest game of all time, There are better MMORPGs out there, but FLYFF is a good MMO to start with, or one that should at least keep your atention for far longer that you would expect considering the price of admision is NOTHING.
