Super Nichibutsu Mahjong 4: Kiso Kenkyuu Hen

Super Nichibutsu Mahjong 4: Kiso Kenkyuu Hen ("Basic Research Edition") is a mahjong game for the Super Famicom and the fourth and final game in the Super Nichibutsu Mahjong series. As with its prequels, it features scantily-clad women in its menus, but uses high-school students and teachers as the game's opponents. The game allows for two-, three- or four-player games of mahjong and also includes a story mode of sorts as the player character (male or female, with three avatar choices for each) takes on opponents in their school's mahjong club.
