Fallout 3 was like 30 to 50 pages? Seriously, topic creator did you ever play a game that had a manual that was hundreds of pages instead of dozens?
LIke someoene said PC games used to have huge ones. Fallout 1 and 2, A lot of the Dungeon and Dragon games had huge manuals, (except Planescape: Torment strangely enough) Arcanum, and many other games. I loved Arcanum's manual btw which is probably my favorite. I love in the back how it goes into some scientific ideas about how elves, humans, etc came about and how it contradicts the orthodox view points of both magic users and scientists. I love the scientific experiments in the beginning of the manual and how magic interferes with the laws of nature. Don't remember how much it actually helped with playing the game but it was so cool I didn't care.
But I guess console games never had large manuals to begin with though.
