This is fucking idiotic. The point is that Nintendo didn't pay attention to what it was doing in writing the manual. The writer need not beat the game, or even play it. He just needs the general idea of the game, and information about weapons and enemies, etc.
The idea that "he" was intentionally put in the manual to misguide everyone's assumptions and therefore set up the "surprise ending" is not the product of a thinking person. The fact is that at that time (and even now, I'd wager), game players naturally assumed that the hero was male, unless it was specifically shown not to be (Athena. etc.) Ambiguous character? Male. Character in a space suit? Male. Unseen racecar drivers, spaceship pilots, tank crews, etc? Male. "Princess Zelda" with long hair and dress? FEMALE. There is no need to reinforce the natural assumptions EVERYONE makes.
*ring*--"Hello?"
(caller)--"This is Jimmy from Nintendo. Are you playing Metroid right now?"
--"No, but I guess I could be."
(N)--"Well, just remember something.."
--"Yeah?"
(N)--"The next time you play Metroid.."
--"Okay?"
(N)--"No matter what you may already think.."
--"?"
(N)--"Samus is ACTUALLY a man! NOT a woman!"
--"And?"
(N)--"That's just it! Don't you get it?"
--"No, not really. I guess I already figured that, but whatever."
At any rate, if you still want to remain in the little fanworld universe where all contradictions and mistakes are explained away with elaborate attributions (see Star Wars boards), then I'll have to make a final plea to the remaining micron or two of your mind not consumed by stupidity:
When you make a surprise ending, you do it by going against or away from the audience's assumptions. You can either build something up so that the audience thinks they know where it is headed, and then change course, or you can play on the audience's natural assumptions that they bring woth them.
The surprise ending cannot contradict the rest of the work. And the rest of the work cannot contradict the surprise ending. "The Sixth Sense" is an easy example to work from: The surprise ending is enabled because WE (the viewers) are not expecting an entire movie to be based on a dead person's experience and perspective. And it works because it is consistent. You can go back and see how the clues were there all along,but we misinterpreted them based on our natural assumptions. THAT is what makes the surprise ending so entertaining. Not that it is unexpected, but that it allowed us to believe one thing but actually mean another WITHOUT contradicting either belief.
The Sixth Sense does not have text at the beginning that says "Bruce Willis is alive and well all throughout this movie." Why? Because we already would assume so, and (most importantly) because it would not be consistent with the movie.
Go ahead and think of every "surprise ending" you can remember, and see if you can remember a time when the work itself flat out lied to you so as to surprise you later with the "truth".
By your reasoning, we would see surprise endings in every movie and game from here to eternity. All you have to do is lie about the ending. Let me see if I can make some surprise endings work out via manual inserts:
(Combat)--"You and a friend are in command of two completely disarmed tanks that are incapable of firing."
(Super Mario Bros)--"The Mushroom Retainers are a deceptive people. We know that the princess was killed several years ago in a border dispute. This does not prevent the Retainers from claiming that "our princess is in another castle!", but now that you know the truth, you will not be fooled into believeing that the princess is actually alive and in the castle of world 8. You know she is dead and will never appear in the game."
(Zelda)--"..and in the end, you will have to fight Ganon. A wild and wily foe, your only hope of defeating him is by hitting him with bait. A master of disguise, Ganon will conceal the damage done to him by the bait. Do not be fooled! Do not resort to magic swords or silver arrows! These will only anger Ganon, increase his life meter, and waste precious bait attacking time."
