Hypothetical question regarding Super MNC...

Yatterman's topic (about someone who won Fortix and pestered him as soon as the giveaway ended) got me thinking about the "right" thing to do in other situations... like Super MNC for example.
Would it be wrong to mark a giveaway as "Not Received" if the giveaway was for Monday Night Combat but you were given Super MNC?

Since you technically never received the game from the giveaway, Monday Night Combat, I would have to say it is acceptable to mark it Not Received.
Anyone else think differently? And keep in mind that saying it's not acceptable would run the risk of invoking the "slippery slope" argument, because then someone could make a Skyrim giveaway but give out Fortix.
