Which version of FF1 are you the most pleased with playing? To my knowledge, it's been released three times in the United States, as Final Fantasy, Final Fantasy Origins, and Final Fantasy: DoS.
I personally prefer the original. The graphics are archaic as hell, and the music is awesome, but due to the lack of technology, is unfaithfully rendered.
But that didn't stop me from playing it in 1991, enjoying the awesomeness of the game, many times over.
It has a certain charm to it, and it seems much more difficult than DoS ( MP ). The limited space for equipment made the game more challenging, and you had think things out a bit more. You couldn't just keep every treasure you found. There were some that you'd just have to leave behind.And that's okay with me, because it makes for a more interesting game.
EDIT - Can a mod add a poll to this thread if possible? I meant to have the 3 games as poll options, but forgot to add the poll when I submitted the thread!
