Alright, to someones previous comment about beating the ruby and emerald weapon. There is an item for the underwater one to let you fight more than 30 min which is pretty much necessary. Other than that KotR, Mime, and W Summon I think is what did it. A few Phoenix summons too.
As far as best FF out. My vote is for 7 and 2 (first one for SNes) The story for 2 I thought was really could and drawn out and a huge game world with lots of things to do. 7 was an amazing story with good graphics at the time. I've tried to play it again, but my machine messes up because I haven't put an emulator on yet, too much power. As far as the remake of FFVII for PS3, they did the first level as a tech demo for the PS3. There is talk about redoing it, but nothing for certain. There are two groups, the HELL YES THAT WOULD RULE and the You will ruin the game trying to remake it. From what I remember, they are doing a game for PSP that is a continuation of the FF VII story line, but I think it's a prequel having to deal with Cloud and Zack it's called Final Fantasy VII: Crisis Core. The PS3 has I believe 2 FF XIII's coming out. There is Final Fantasy XIII and Final Fantasy Versus 13 with a mobile version called Final Fantasy Agito XIII.
