As mentioned by several others in this thread The Pharos was the final dungeon. The Sky Fortress Bahamut to me was never suppose to be the "final dungeon" just a rather large setting for the final boss fight. It is true The Undying is nowhere near the strongest enemy you face in FFXII & I like it that that way. The main storyline takes place in a small part of Ivalice but there is a much bigger story & history to be explored within the game. Just read the Bestary file on the espers & later hunts the story of Vaan & co is really just a small part of whats going on.

On another point the final bosses in all the PS2 Final Fantasy games are way too easy when you compare them to what you are expected to face in the earlier games in the FF series. Since FFVII & FFVIII th games have steadily got easier. For this I blame the series popularity. The more each game in the series sells, the more Square Enix will have to cater to more casual RPG gamers, those who just play the main storyline & dont bother with side quests etc.

Final Fantasy XII is a testament to this idea but still I loved it otherwise I never would of put 140+ hours into it whilest I'm suppose to be doing law course work.

Maybe with the series leap into the next gen with Finl Fantasy XIII on PS3 will provide us with the epic final boss fight we are all lusting after.
