AEON GENESIS 
Chaos World
Chaos World is an RPG for the NES/Famicom which was -way- ahead of its time. Fourteen playable characters, an Adventurers' Guild which Final Fantasy Tactics ripped off for its tavern jobs, twenty hours of gameplay, create your own character, a night/day cycle, an involving storyline... I could go on forever about the game. It seriously deserves your play time, so go play instead of wasting your time reading this :)
