Once again very vague article about what looks like a japanese only board game for N64 that I can't track down if it was ever released. Any ideas ?
Just going by the name, there's a game called "Kira tto Kaiketsu! 64 Tanteidan" and it is a party or board game or something. Seems like there's little English language information on it, or at least my quick searching only revealed little... No idea if it's the right one.
translated: Detective Team is a multiplayer game proposing a challenge on a multitude of levels with differents puzzles. Each time you will start a game, its new-generated levels that will appears. this game seems pleasent, but only is destined to the Japanese public.
