Might
and Magic Official Strategy Guide
There's also an official strategy guide from Prima (click the above link to buy it now from Amazon). I haven't seen the guide yet, so can't offer an opinion, but if you've got money eating a hole in your pocket, go ahead and get it too! :)
If you enjoy Might and Magic IX, then you might also enjoy the following: (These are my personal recommendations):
The Heroes of Might and Magic series is a strategy game that takes place in the Might and Magic world. Strategy games are different than RPG's -- rather than directing a small party through an adventure, you take on a god-like role of managing an entire civilization of adventurers. If you like strategy games, and you like the rich Might and Magic universe, then this game is for you.
Arcanum:
Of Steamworks & Magick Obscura
Arcanum is one of the most enjoyable games I've played in years. It's take a new and original spin on adventure by blending technology and magic together. Your party can include fighters, mages, and gun-toting technologists. Sierra did a masterful job of crafting this game, with well written dialog and good use of voice actors. The perspective is third person, much like the Baldur's Gate type games.
