I have the CE Strategy Guide.
Its pretty nice, but has some inaccurate information within it.
Such as claiming that if you had 1 INT, all your options for dialog would be VERY stupid (Like how it was done in FO1 & 2). I've made a 1 INT character, the game plays exactly the same, I was pretty disappointed.
Reading isn't only fun, it's fundamental.
The book says, and I quote: "Intelligence affects
occasional conversations you can have with Mohave Wasteland folk."
So often these boards are filled with people who fail at reading.
