When it comes to MMO content everyone has different pieces that give them the most joy. So what's yours?

For me:
* Holiday events - The holiday things probably could be lumped in with the side quests and the collecting, but I'll call it out separately because I like the story bits behind them. The halloween event this past year was pitch perfect.

* Aquapolis - There is a a thrill when the goblin drops into the room or you get the save when you've picked the wrong door. All that and minions and glamour. This content is pure dessert for me.

* Side quests - I know there is a dislike of some of these, but I really enjoyed the sophisticate, the moogle delivery, and (mostly) the hildibrand quests.

* Collecting - The best way to get me to do something is to put a minion or an emote at the end of it. It won't work for all content or it may be an expansion before I get to it, but it will work for most. If they ever add in something akin to WoW's collection feature (including toys? please?) I'll probably never unsub.
