And which final boss would that be? The final boss in Rank mission 5-2? The final boss of Zilart Mission 17? The final boss of Promathia Chapter 8-4? I'm sure there will also be a final boss of Aht Urhgan... sadly the game doesn't really offer a final final boss.

As for me. I'll probably stop playing when it either drives me nuts or it goes offline forever. My list of goals are nearly impossible within the confines of the game as it currently is mostly due to storage issues within the game.

I would love to have all of the gear that I want for my BRD which is almost impossible as it is. I'd also love to eventually take the rest of my jobs to 75 and have all of the great gears for them as well (not that bad considering many of them are shared) but the problem is space and it's already becoming an issue. There are a great many Ra/Ex piece of great equipment in the game. Even to have all of the great Ra/Ex things I can have for my BRD might be impossible with the current storage situation. I keep piling these Ra/Ex things up in my MH and I'm not able to mule them. A few examples.

Joyeuse
Rostrum Pumps
Suzaku's Sune-Ate
Tamas Ring
Bomb Queen Ring
Opo-opo Crown
Star Necklace
Minstrel's Coat
Gaudy Harness

This is only a small pinch of what gear I currently have not even mentioning the loads of things for my non-main job like...

Carbuncle Mitts
Rogetsurin
van Pendant
Moldavite Earring
Tavnazian Ring

and the list goes on. Eventualy leveling all jobs to 50 I'd want their individual level 50 JSEs and endgame I'd like to have full god gear (not all of which is Ra/Ex) and Zenith gear and that's only for my mages... that doesn't count Relic Gear, AF+1 and then eventually Ajburation gears for other jobs. As you can see it is nearly impossible to meet my goals because of this current space limitation. Sorry to get completely off topic so here is what I would want in a perfect world.

All jobs to 75 including great gear for them all (most of which is Ra/Ex)

All crafts to 60+1... one at 100+3 (or more depending on the craft) fishing to 100+whatever it can get. A few level 100+ crafts on mules such as Cooking and Alchemy.

All story lines completed which requires me only to finish 1 BC for ZMs and the rest of my Wind and Bastok missions... pretty easy and I'll probably be done with this soon. Of course there is Aht Urhgan on the horizon.

I'd like to finish all individual quests. I'd say I have over 50% done. For particular places I have a much larger percentage done. I have over 90% of the individual quests in Sandy complete. Most of the ones not complete are stuff like the LuShang's rod quest (working on it) and the AF quests for jobs I don't have up yet.

There is all of this and potentially very much more in the game left for me.
