I actually do remember using the Play Online service for Final Fantasy IX - Horrid concept though and of course now we have GameFaqs
The problem with Strategy Guides in this era is that they don't consider DLC. I bought the Hardback Deluxe guide for Final Fantasy XV and now that the game has had a billion updates it's barely even the same game presented in the original guide - Heck later updates even let you control the other party memebers but in the OG version it was just Noctis!
i miss the tradition of buying Strategy Guides but they sadly don't seem to be such a worthy investment any more
... Would I buy the Final Fantasy XVI Strategy Guide fomr Piggyback... You damn right I would!
