I hope, that Final Fantasy VII: ACC is not only for Japan and North America...
'Cause I want this movie so badly ;_; It looks sooo great... all the new scenes...
New scenes !!! I gotta say, I wasn't even going to watch the trailer untill I saw you mentioning new scenes! And I gotta say it looks great. I'm so glad I'll be going to Japan this April, because I was already planning on buying this version of the PS3, I have to admit, more for the FFXIII demo than for AC (which I also love, but as I already had it in DVD it wasn't such a hype for me) but with this much extras it is much more interesting!
^ Congratulations!! 
See I had a different experience, and the final boss was perhaps the hardest end boss in a FF game for me, more so than one-winged Sephiroth in VII. I had quite high-level characters though, perhaps the game adjusts the difficulty as such for the end boss?
Congratulations on my part too!
And I have to agree with you, I found this son of a gun very hard... But I believe the main problem with him is the equipment we may or may not have. My cousin had all magic, the best equips and all and he was a breeze. I was level 99 but without all that, even so he was hard.
Just to make a point, I don't know if you guys heard of the 1 22 333 FFXII Challenge ? Making it short, that's the level of your party, and I've seen a video on youtube of people beating the last boss and some others in these levels, HOWEVER, they use some amazing killer strategy that make us "mortals" feel like idiots. You should check these videos out, just for fun!
And now for my part, I just came back to playing FFIV on the DS, man, what a game! It's so good I can't even believe I stopped playing it in the first place, no wonder the long time fans say this is the one that really made it all better!
