Youkai Douchuuki was Namco's very first 16-bit arcade game. It was never released in the US due to heavy Japanese cultural themes. You play as Tarosuke, a young boy who must travel through "Jigoku" (the Japanese concept of Hell) fighting off "yokai" (mythical Japanese monsters) on his way to his final fate, as determined by Buddha.
Ever want to go to New Zealand? Well, here is your chance. In New Zealand Story, you play as a Kiwi bird that must save his fellow Kiwi birds from being captured by an evil seal. It's a very bizarre and forgotten platforming games.
