it has better graphics. more advanced everything, 4 extra dungeonswith bosses from FF3,4,5 and 6 and its much, much, much easier than the original FF1. FF2 though is still just as difficulkt as far as i know. ive not played the originals but FF" had some very hard parts. their both great games and if you dont want to buy origins for PS1 or the original for snes/nes (was there ever a nes version?) id definetly buy DoS.
