BACK FROM THE GRAVEYARD Y'ALL

I just wanted to talk somewhere about how INSANE the final boss for this game is. Wow. Probably the best final boss battle I can remember. You know how sometimes you overlevel and the final boss of the game is a cakewalk? Nope. This straddles the line between final boss and superboss. I had used all but one curative item, including stuff I didn't even realize I had, when I just managed to nick his heart with a magick arrow and that was the end of it. It took probably an hour for the whole combined ending sequence, which was incredible as well. It felt both cinematic and interactive in an engrossing way.

That said, I feel a little cheated that the end of the main story isn't really the end. I've never seen post-game content that seemed so much like intended game content. (It's kind of like the future arc in Tales of Graces f, I suppose...I really need to go back and finish that too.) There's more story, harder enemies, a huge mega-dungeon, areas you could never access before...what am I supposed to do? I feel like investing more time into this game would start being less rewarding, but I also feel like I'm abandoning it if I quit now.

Did any of you guys who played this game beat it, and if so, how much post-game did you do, and was it worthwhile?
