Phantasy star 2 comes with a fuckhuge full color book that holds your hand for the entire game. It tells you what item is found on each floor and marks the up/down teleporters gor every dungeon. The book also says which items can be used as free spells in combat.

Enulator people seem to not know this book came with the game, the same way they never knew the first zelda game came with a world map.
