Awesome quiz! I'd never heard of the Wii Vitality Sensor before. I think you should except strength for strength training, though. As for who I'd like to see next, I think Dark Samus would be cool. I'm a huge Metroid geek and I'm interested to see if you can stump me on a question or two. Why Dark Samus instead of Samus? Because I haven't played every Metroid game yet, namely Other M and Hunters, so I might miss some there.
I’ve only ever played the original Metroid and Super Metroid, but I’ll try and track down the Metroid Prime Trilogy. I wanna make sure to find the most obscure things about Dark Samus so I can stump you >:)
