So I recently become addicted to a set of videos on Youtube known as "Let's Play",
Basically its you watching a play list of someone playing a game...boring you say? to some yes, but when these guys play old classic games that I never got to finish years ago, and even some new games, its pretty entertaining. Of course some of them are hella long...one spanned across 150 10min videos. Most offer pretty good strategies (starcraft 2)
A few good ones I've subscribed to are
