I got it for Oblivion and used it every time I played the game. I bought it for this one, but I am having so much fun trying the quests by myself it is hard to use the book. I love it, and it is EXTREMELY detailed!
Absolutely. The guide for Oblivion was very helpful, so I went and picked up one for Skyrim. I don't plan on using it much for my first character, but I'm definitely going to be referencing it for later, more comprehensive, playthroughs.
Bought it with the gane at half price, should arrive this morning in the mail. Hope its as good as the Fallout New Vegas one. The quest walkthroughs are to be left for the 2nd playthrough just to be sure I dont miss anything but the character building section
was good in the FNV guide to at least skim through as the game was installing on HDD and as a bathroom read.
