I wanted to share with you a few random thoughts and explain why this game was very different from the previous one.
About the chances of getting the prize, regardless of what has happened in this specific game, nobody has a way to tell how many correct answers have been provided by the players.
You shouldn’t find it strange or unlikely that most players provide just one correct answer. That’s exactly what happened this time, so the chances of getting the prize with just one correct answer were actually pretty high!
About the game itself, it was intentionally much more difficult than the previous one (the “quote game”). That game was focused on Lucas adventure games, which are probably very well known by this specific community of players. On the other hand, this “sidekick game” didn’t have one single Lucas game in it and it’s no surprise that all players correctly recognized Freddi Fish, which is a game by Ron Gilbert.
The more you move away from Lucas and Ron, the higher the chances that the resulting game will be more tough for the users of this forum.
The higher difficulty might also be a consequence of another factor: the answers in this thread suggests that a good percentage of us didn’t play many of the adventure games of the last decade. In other words, the percentage of active and frequent adventure gamers in this forum doesn’t seem to be very high and that made this “sidekick” game more difficult.
I have enjoyed the fact that a more difficult game has created unexpected dynamics. The idea that somebody might win with just one correct answer or even zero answers amuses me. 
So, the next game will probably be just slightly less difficult.
I leave you a little hint about the next game:
