It's time for another pair of videos for Co-Op Classics. This week, we look at an early co-op game known more for the characters than the co-op: the original Mario Bros. arcade. Our second video is from the co-op golden age of the early 1990s: Sunset Riders.

For quite some time now, I've been on the lookout for the oldest videogame featuring co-operative gameplay.  Of course, this all depends on your definition of co-op.  Here at Co-Optimus, we don't consider team or squad based games to be true co-op; working together against a non-human opponent would count, though.  This disqualifies the first titles that popped into my head, like Atari Football and all the crazy Pong clones that featured more than two players.  (To my knowledge, you couldn't use an AI player for these games.)  The game we'll look at this week may not actually be the oldest co-op game there is, but it certainly predates early classics like Gauntlet and Contra.  Mario Brothers may be famous for other reasons, but it's still a solid co-op experience.
