I think for the me the biggest thing is the whole gaming industry slowly failing and new games coming out not really being worth their price. For the fraction of the cost a new game that'd probably last for a few days or a few weeks, I get a full month of something to do.
And because part of the game is sitting around waiting for dungeon/raid/whatever queues, I can do other things while waiting on those.


While that might work with other MMOs as well, FF14 specifically is probably because I like the FF series and is one of the better MMOs out there.



Also, catgirls.
