File this one under "potentially mind-blasterizing", Mariachi Mayhem was pitched to CBC's Dragons' Den television series and is currently in the running for "Top 3 pitches". Creator Fuzzball853 hopes to turn it into an Xbox Live Arcade title. Definitely not the snazziest game to grace a hi-def television, but in the right hands it could be something awesome. The only really obvious miss? There's no darn mariachi music in the pitch!

Thanks to Guin for the tip!
