MtP was so unexpected! It was so different than I imagined, and I loved it! In my opinion, I think it was a good idea not to unmask the pyro in the video, so it won't deter some players to playing as a pyro again because of what he/she looks like or where he/she is from. Anyway, it was so enjoyable and it makes TF2 feel like a complete game.
Spoiler Alert: My favorite parts was the red scout's interview and the trapped blu medic. xp
