It's good to know, Jafin, that the guide does have some good points. I guess our point here is:
A) The inaccuracies in the guide can have players literally going 'round in circles looking for something the guide says is there but isn't.
B) The tables are incomplete, and often contain inaccurate information on what is there.
C) All the good points in the guide can be found in online walkthroughs (like Rick's site) or have been covered here on this forum...
