I seem to be in the opposite situation as a majority of people. I have had the benefit of actually listening to the soundtracks of 5 of these 7 games regularly (read: just about every day for years), so after confirming all of those and figuring out the other 2 (based on instrumentation, obvious melodies, and such), I submitted my entry.
As a number of people have pointed out, this contest appeals very much to game soundtrack aficionados and even then only to a small subset of them. But as with any content-based contest, it all comes down to your tastes, habits, and skills and whether they match with the contest. I may seem to have a bit of an upper hand for this contest, but if this was any sort of art submission contest I would have absolutely zero chance of winning.
So to everyone attempting the contest, I say, "Good luck." To everyone who has given up or never held any interest in it, I am sorry this contest was not your cup of tea. I can only hope that maybe this has brought video game music more to your attention. There can be some truly fantastic music in some of your favorite games.
