Building a retro game library isn't just about cartridges and consoles; the right strategy reference can make old games far more approachable. But with two very different vintage guides on the table, the decision isn't automatic. One is a broad 1990s secrets compendium for the 3DO, and the other is a focused 2000s guide for Kingdom Hearts Chain of Memories. They both sit in the trade paperback format and both target Games & Activities readers, yet they suit completely different collections.
Quick Verdict
If your shelves lean toward the 3DO and you want one book that covers multiple titles, the 3DO Game Secrets Book Two is the broader, more reference-minded choice. If you're a Kingdom Hearts fan who wants a guide that follows Chain of Memories closely, the Kingdom Hearts guide is the focused companion that lines up with a single playthrough. They're both genuine video game strategy reference picks, but they answer different needs.

Product Notes
3DO Game Secrets Book Two

This 1996 volume from Sandwich Islands Publishing collects secrets, hints, and tips for a range of 3DO games, making it a sensible companion if you have a stack of 3DO titles and want a single book to flip through. The author credit includes Zach Meston, J. Douglas Arnold, and Doug Arnold. The trade-off: the copy is rated Good and carries an inscription, so it's not a pristine shelf display piece. If your gaming focus is squarely 1990s 3DO, this one covers more ground than a dedicated single-game guide ever could. The breadth is the main draw, and the condition is the catch.
Kingdom Hearts Chain of Memories Official Strategy Guide Game Boy Advance Poster

This 2004 DK Games guide stays tightly focused on Kingdom Hearts Chain of Memories for the Game Boy Advance, offering a complete walkthrough plus a fold-out poster. Written by Greg Sepelak and Beth Hollinger, the 144-page guide shows very little use, with a Very Good condition rating. The limitation is its narrow scope: it covers one adventure, so it pairs with a focused playthrough rather than a general-purpose reference. If you've already committed to replaying Chain of Memories, the detailed route and poster make it an easy call.
Final Choice by Use Case
Go with the 3DO Game Secrets Book Two when your collection centers on 3DO hardware and you want one wide-ranging hints-and-secrets resource, or when an inscribed vintage copy adds character to your shelf.
