I thought days was great, the only things i disliked was the uninvolvement in the disney worlds, not being able to explore really anywhere, camera controls, and heartless with bigger health bars than sephiroth. I got final mix as a present but my parents got it from play-asia.com they also have japanese ps2's since ps2's are region locked. Also instead of buying a whole new console, i just bought swap magic, just search it on google and a couple of sites will show up. Final MIx was definetley worth the extra money, its harder and with more optional bosses, a bunch of new challenges, and a ton of space more to explore inside of Radiant Garden in a place called "THe Cave Of Remembrance"
