Just thought I'd reiterate the fact that this game has more replay value and depth than most other Strategy RPG's I've ever played... With that said, it is one of the more enigmatic games ever released. A lot of time has passed since it's Japanese release and it is still baffling gamers over there (a testament to it's mystery). The Japanese wiki is still active, and here is the newer English one:

Not sure if Aksys is considering a strategy guide, but I'd encourage everyone who has time to do so, play it at least twice. The first playthrough, don't read any strategies or faqs, play on easy or normal (or hard if you primarily enjoy Strat games) and choose the answers and brides that seem like a natural fit for your personality. The second, read as much as possible what others have written, try to unlock all the hidden gems, play for the true ending, chose answers that get you the offspring and weapons for them that you want. Yet it sure would be nice for a deep strategy guide!!!
