Do you have a Famicom, a lot of Famicom games (somewhere between 30 and 50) and two or more friends? If so, you can play the party game that's sweeping Japan!
OK, so it's not really sweeping Japan, but it's popular enough that some folks are filming their "Famicom Party Game" experiences and posting the resulting videos--like the one below--on YouTube.
Note: Although dressing up in Famicom-inspired cosplay isn't required of "Famicom Party Game" participants, doing so certainly seems to add an extra dollop of fun to the proceedings.
For more information on this game, which apparently originated on a Japanese TV show called "Otameshika," check out famicomblog. blogspot.com.
