Interesting...
Scored a 370/600. You should've included more music options (including turning it off completely) or made the one song loop every 4 minutes or so, just so that it didn't get annoying to hear.
The questions asked were very interesting and made me smile a lot when I got to a couple of them -- NOSTALGIA CENTRAL! Unfortunately, most of the questions I got wrong were on NES games that I never played as a child. Also, I think some of the video game-specific questions could've been replaced with questions based on the origin of character names (eg: Who is Mario named after?) or famous slogans for certain games (here's an easy one: What was the slogan Nintendo marketed for the NES?)
Overall, this was a very good questionaire and I hope to see more work from you in the future! Maybe you'll make one for the SNES? =) Good luck and good job!
