dunno about games, but it was a greivous error when i purchased the Pokemon HG/SS strategy guide, the writers didn't know SQUAT about the game and had clearly got their information by grabbing people off the streets and asking them! not only does it only cover the johto half of the game, almost all the information is wrong somehow, according to this, to get pokemon such as suicune and the gen 1 starters, i'd have to trade them in from Diamond Pearl or Platinum. also, you know how good guides have very detailed info on the pokemon in the first half of the game and less detailed info on the ones you get after the elite 4? well this one has sketchy detail on the first group and not a word on any others, rant over.
theres 8 pounds i could have given to a homeless person, or bought my cats some treats with, or got my sister a cheap birthday present, or bought some luch at subway, or...... (etc)
