Indisputably the best GBC RPG ever made, it lives up to the standard that the previous Lufia games set.
To make it easy for us I'll just divide my review along the aspects of a game:
Gameplay: One thing you will notice in Lufia III is that it's long. I'm around three days into the game and yet the only Sinistral I've met was Gades. The dungeons, although long and sometimes difficult, aren't that boring or much of a grind really, and the innovative grid battle system (a system I've never seen before, and I've never seen in any other game even until now) made turn-based battle a refreshing tactical twist aside from the usual norm. The dungeon system in Lufia II also had been executed perfectly in this game, and overall, this is a game which gamers can enjoy for tens of hours.
Sound: The best sound you can ever hear in the GBC. More than just teeny blips and beeps, the music of Lufia III is extraordinarily complex compared to other RPGs of the system. The introduction music (which is a rearrangement of the background music for Doom Island at Lufia I's first scenario) is more than enough proof for anybody.
Graphics: Although the GBC has limited resources, Lufia III made full use of it, making high-quality graphics and realistic-looking environments. Compared to many other RPGs in the system, the game has very refined and well-made visuals, a rarity in the GBC.
Story: We all know the story: The gods, the Sinistrals, control the world via Doom Island, and heroes will come and bring it down. However, a huge cast of characters, each of which have an interesting story to tell, from Seena, the wandering fortune-teller, to Deckard, a noble pirate who brings down other pirates, to the curious Mousse, the Capsule Monster, make for a very great adventure to go through.
Value and Replayability: There's a lot to explore (fans of Lufia II's Ancient Cave would be pleased to see a very large Ancient Cave at this installment), there's a lot to get, and combined with the long story, Lufia III has a lot to offer for its buck. I'd say you won't regret buying this game.
Overall, Lufia III is another RPG classic, and among its predecessors, they set the standards for an excellent RPG in their resident consoles, and RPG gamers would regret not playing this game; it's excellent, and no doubting it.
