What did you find most intresting about Phantasy Star(s)?
PSI: The "mazes". (i.e dungeons)
PSII: Nei. Never before had I played a game where a nova character had actualy died. It gave the game much more depth afterward, as though I owed it to Nei to keep playing to the very end.
PSIII: The fact that the entire "world" was actualy a giant spacecraft. To this very day, it amazes me. I still haven't seen an original idea nearly as unique as that. It just boggles my mind to think about a spacecraft comprised of six bio-spheres that fully support life, completely independant of a planet.
PSIV: Magic. Magic had been hinted at during PSII and PSIII, but until PSIV, it had never been given a name, nor had it been used by a playable character. The entire mystery behind it has always intrigued me. In reality, we use Magic as a word to define an illusion, but in Phantasy Star, an illusion would be called "a trick". Even Technique is on a higher scale that Magic by our standards. The whole mystical power has always intrested me.
