Blue Breaker isn't that hard to play through. The FAQ is enough really. What makes BB hard to play through is the weirdness of it. For a large portion of the game, you basically have nothing to actually do. Just wander from town to town. 90% of the dungeons are mostly optional too. The common idea is to recruit all the girls first, but again you don't ever have to do this, it's just something you can do. BB is a weird game that plays quite differently from everything else, it takes awhile to really get into its' pacing. But it's a great game once you "get it" per say.
