[quote name='Dark Lord Greg']are Piggyback guides better quality/more limited than the Brady or Prima guides?[/QUOTE]
Piggyback guides are hands down the best guides I have seen in my life, both in terms of presentation and content. I used both of their Collector's Edition guides for FFXIII and RE5 and I never had to go to the Internet for anything, everything was right there on the page. Also, very very beautiful; you can get an idea of how their guides look at piggybackinteractive.com. When people talk about quality guides, some mention FuturePress and I would agree, they're better than Prima/Bradygames, but I still think Piggyback trumps them.
