dude.... you did not beat the game, In my eyes the below pre-requisites qualify as beating the game:
Attain all AF for you job whether you use it anymore or not : P
Attain Lvl 75 and.......unlock final weaponskill for your main weapons you use
Rank 10 - all 3 cities
Max Fame all cities - do a few quests for more background and stories
ZM 17 - defeat all
Defeat Divine Might BCNM - assisgning this prerequisite because it is probably one of the most fun fights and is related to zilart mission storyline.
CoP - defeat all - this is still not complete as new stuff will unlock shortly
Kirin Captivator title obtained (also have defeated the 4 other Gods as well as the NMs that drop their pop items)
Dynamis Interloper title obtained - all areas (demonstrates you have gone and defeated the main areas as well as have defeated the DL)
Played Balista more than 5 times
having actually used or borrowed a kraken club for a short time ^^
*having actually seen argus (at least once in your in-game career)
Having actually seen if not engaged or defeated all 3 of the Land Kings (BCNM counts)
Have beaten an actual beast-seal and kindred seal BCNM and attained loot or money.
Have beaten an ENM.
Have claimed and killed an NM before and gotten the good drop. ^^
Have been in an all JP PT
Have actually gotten a JP to join your PT
Have learned a little bit of Japanese in the process of playing this game
Everything else in game is for more enjoyment or loot or E-Penis gratification.
The above would qualify as beating the game as their is no more actual story to follow after other than upgrading Relic, which I do not see a majority of people even attempting because it is not exactly necessary for FFXI story completion. Some of the above is not related to story completion but they make for more of the more memorable moments in one's in-game career.
So you better come back untl you have done all of the above :!:
