One of my absolute favourite game series was the Megaman games. They were notoriously difficult, but they were also brilliant once you got good enough to get through the level.

I found this episode hilarious. One candidate for quote of the video is "It's just death at every corner". Also good in the series was Teens React to Nintendo (although on a different YouTube channel), which stars the girl who plays Arya Stark on the Game of Thrones TV show.
