Don't freak! It's all about video games!
It's like Jeopardy, except much faster, and all about video games (and I think 2 science questions). Look for more categories soon! The categories are random, so chances are that the next time you play, you'll get a new category. There are 7 overall. More will be added soon.
IM me if you want me to explain to you the "Video Game, M.D." category.
