Epic Battle Fantasy parodied Final Fantasy style battle systems by having well-animated characters react in funny ways to getting hit, and by having crazy skills such as "Power Metal" where the music from the blaring speakers damages your enemies while healing your metalhead party. It was also a good example of a FF-style battle system; as a game, it worked. Epic Battle Fantasy 2 was more of the same with new enemies and animations.
Epic Battle Fantasy 3 wraps an adventure game around the battle system. Players now get leveling up, a skill system, lots of NPCs giving you quests, a few minigames, one puzzle, and an awesome soundtrack by Halcyonic Falcon X. The adventure is straightforward -- follow the single path -- which can be a good or bad thing depending on how you look at it. I appreciate the reduced playing time from never wondering where to go. What really counts is all of the little things that went into the game: the odd NPCs that are on nearly every screen of the map, the banter between your party members during battles, the large number of skills and items, and the large number of animations. Binding it all together is the solid core of the battle system, presented with high-quality artwork and music. The result is one of the best flash games ever made. It has about a 12 hour playing time.
