As usual, fusional doesn't contribute anything to a discussion, let alone one with a legitimate foundation.

Ideas that should be added in the form of content, to give the game more depth and better atmosphere while simultaneously giving the player a deeper understanding and appreciation of the world are as follows:

1) Side quests: Not only should these small quests yield experience and other rewards for completion (which they definitely should), but they should be done in a similar form to FFXI's quests. Each one should have it's own little story and premise, that as you go through it, you learn more of the world and it's going-ons. Each quest should be fairly unique, and each one should be it's own story that ties into the main world in a small way. Artifact quests (weapon, armor, etc) already behave like this to a degree, but I want to see deeper stories.

2) Marks. Marks. Marks. Give players a reason to kill an NM - marks fulfill this purpose. Provide each tavern, inn, or guild with some form of bounty board where the player and the party can go to pick up some quick quests in the form of hunting and killing NMs. Not only that, but give NMs their own unique spawn method - whether it's a window, force pop, a special ritual, or some other popping method, and make questing to kill each Mark a small adventure in it's own right. If you want, make them repeatable - offer small rewards for completion of the mark, varying with difficulty and rarity.

3) Housing. I haven't touched much upon this subject yet, but it is a popular thing in FFXI for people to pay special mind to their MH, so they can place their own style in it and make it their own space. People do the same with interior decorating IRL - give us quality housing in ARR so people can design their own home and add onto it at their leisure.

4) Chocobo raising: another subject that has been touched upon, I'm sure, and will hopefully allow players to fully breed their own chocobos and even have them stay on their 'ranch.' But, make it less annoying than FFXI - I left the game for several months and came back at one point. I had THOSE 3 months worth of cutscenes to catch up on for my chocobo.. what a drag that was.

5) PvP Arena. Allow players to do battle with one-another in a controlled environment. Up the ante, and even let other players view the activity - maybe allow spectators to place bets, so that they can make (or lose) a little bit of gil while having some fun. Even add to this with tournaments, so people can finally get some bragging rights and even claim some reward in the process.

Other content includes dungeons, bosses, HNMs, and all of the other things. Depending on the complexity of all the content, I'm sure some of it could even be interlinked, like HNMs being Marks, etc. I'm just hoping that they make a REALLY good loot system for ARR, so people can get new stuff on a fairly regular basis..

Those are my five cents~
