Family Pirate Party for WiiWare.
Actually, as it turns out, the game stars the same family seen in Family Glide Hockey, which released earlier this year and was pretty awful. Family Pirate Party is a board game that has players sailing to various islands, plundering treasure and participating in "hilariously exciting minigames." Hey, the Wii could always use more minigames, right?
Fun fact: Family Pirate Party is made by Arc System Works, the same developer that brought us Guilty Gear. We're confused too.
