From Xfire: "Back in the Dark Ages called the early-90s, there were many conveniences that were not available to the average gamer. It is easy to take for granted nowadays, but the very idea of a complete game map was reserved for those who could buy them from magazines or player’s guides. And in extreme cases, you could actually call a special number to get some help when you are stuck! Nintendo, in particular, had a hotline manned by Nintendo Game Play Counselors (as they were called). This hotline was active and operated in-house by Nintendo for a whopping 18 years (1987 to 2005).
One recent discovery related to this is the Super-Secret Super Metroid Map. This was used by these Game Play Counselors to help weary players lost without a clue… a map painstakingly hand drawn by one of the game’s Japanese developers!"
