Every time I play XIV, I am thankful for all the possibilities and things there are to do. Between gathering, crafting and dungeon raiding, the game is just getting started.
Starting an FC is always fun, and so is building a fleet of airships and submarines.
Decorating houses is fun, there is a community/game within XIV itself just with this part of XIV. Check out housing snap or Eorzean Estates.
Gold Saucer : need I say more?
Map parties : If you haven't done these, don't submit your "crybaby unsub " post jussssssst yet!
Wondrous Tails : what a simple yet productive way to do recycled content.
PVP : I don't do or enjoy this, but many do! Another feather in XIV's cap.
Misc: Diadem, Eureka, Palace of the Dead: Take them or leave them, you cannot deny the added versatility they give this game.
Linkshells: Believe it or not this game has great community. I won't say it's better than any other game's,but it's there, and it's great if you take the time to get involved with some type of group i.e. map or hunt parties.
Events and content : Square does a great job of adding new stuff consintently, it isn't always rockstar content,but they always try,and alot of times stuff is new and unique.
In summation: This game is alive and well. I love it, and I love my server Sargatanas.
