Amazing new gameplay and story. Square-Enix wiggles in another masterpiece.
The gameplay alone, RPG-wise, is amazingly unique though still classic. The battle system alone is an amazing tribute to Square's forever changing worlds, and "World ends with you" puts itself easily up there with Final Fantasy and Kingdom Hearts. What makes the battle system so amazing is the how fast paced it gets, and not just a click/select kill fight. The 'armour' system of wearing brand name clothes and getting boosts depending on their popularity is a clever move away from magical artifacts and heavy plate mail.
The pin system reminds me a lot of the materia system from FF7, though still unique in its own way. The only thing Im not partial towards is the music, though it suits the game pretty well, its not my preference.
The use of the DS' unique build also helps make this game a one of a kind. 2 screen battles, though confusing at first, make it insanely fun. Square Enix has brought forth another brilliant series, one I can easily follow.
