First let me say that I had second thoughts about getting this guide, however I took a chance and, with one exception, I'm glad I did.
-Great introduction for new players to the HM series.
-Very good 'catalog', lists every item in the game.
--For weapons, farm tools (which can also be used as weapons), shields and accesories, it gives all the items stats, bonuses, etc.
--For seeds, it lists all the growth times (when they can be grown, how long they take to grow, etc.)
--For recipes, it lists all the ingredients you need to make them, and what levels are good to start making them.
--For potions, medicines, herbs, etc. it lists there effect and where they can be found.
--Plus a complete list of all monsters, their total HP, strengths, weaknesses and there use on the farm (or in combat).
-Very good character guide, with complete (and so far what I've found to be acurate) schedules for every character.
-Complete 'wedding bells' guide, lists all potential brides, their likes, dislikes, requirements for marriage and their complete schedule.
-Great boss strategies.
-And last but not least, a complete walkthrough of the entire game, including the best times to upgrade tools, what monsters are best to catch, the best time to make big purchases (such as house upgrades) and some great money making tips.
And the bad:
The cave maps. This is my only complaint with this guide. The maps themselves are fairly good (though they can sometimes be confusing) it's there location in the guide that gets me. I always like to compare maps with walkthroughs, I do in every guide. However in this guide, all the maps are in a different section than the walkthrough. Meaning if you, like me, like to compare them with the walkthrough, you'll be doing a lot of page-flipping.
Overall, I would reccomend this guide to anyone who might have any questions about this game.
