I picked up the Prima Guide for BI a couple days ago--just a warning, and I imagine this may have been said by someone else before--but it's really, really bad.

1) As with the Rome guide, there's no information on morale or speed for individual unit stats.

2) Tactics and strategy is laughable. E.g. each playable faction has a synopsis, from which the in-game description makes up about 50% of the description. One of the short paragraphs written on the Alemanni goes as such, "If you bribe the Frankish diplomat and he accepts your gift, he becomes your diplomat." Thanks.

3) Some of the information is plain wrong (caveat, this may be a function of patches, but my suspicious is that the editor was just lazy).

4) The layout and format is amateurish and unlear.

I am hopeful that the next iteration of the Total War franchise is paired with a more useful strategy guide.
