I wonder if a hint system using a program could work better for someone stuck at a problem...
IE:
Enter location: Colussia (Select from a drop down menu.)
(program looks up Colussia data)
What are you looking for: Twin Trade's (Select from a drop down menu.)
This is located on the road leading to the church.
or:
Enter location: Colussia
What are you looking for: Illustration 112
It is located in a house by (where ever it is) in a safe, the code is 4624.
This could help more than a walkthrough because user doesn't need to find which time you were in colussia to find out about the safe code.
BUT, this would take a LOT of time to set-up, but, it may be easer to update later.
It could also list all the monsters, where they could be found, and where their legendary is located.
All the Illustration, cards, pictures...
How to get the different H scenes...
When and where each of the quests are given, where to go and what to do...
and all the characters you would come across, altho, some of them are found in different locations at different times.
