There's usually copyright and printing history info-- AKA the indicia-- on the page to the left of the table of contents. You might find some useful info there to go off of in further searches.
In any case, your find reminds me somewhat of the BradyGames'
Oracle of Seasons / Ages Official Pocket Guide I found some time back. (the "two" on the far right in the pic below)
It also somehow reminds me of the Scholastic choose-your-own-path books they put out, which featured strategies in the story.
Good luck in your info hunt...
