This is amazing. I think it'll make a good party game also, especially if the attendees are well-traveled or international.

edit: Would be amazing if you added a competitive mode also, where two or more parties would get the same series of videos (randomly generated from a unique URL or something). And see who can get the most points out of 100 or so. Even better of the options are labeled A-D and randomized so groups in the same room can discuss which one they want to pick without leaking information
