Milky Way Delirium
In this game, the players have a square of asteroids with numbers on them. The number corresponds to the number of microgames that must be played in order to claim the asteroid. Complete the required number of microgames, and the asteroid is marked as belonging to the player that completed the games. If a player claims an asteroid that is in a vertical, horizontal, or diagonal line ending with another one of the player's asteroids, every asteroid in that line falls under possession of the player as well. When all of the asteroids have been claimed, the player with the most asteroids needs to face the microgame of a giant robot, any asteroids that had not been claimed remain as an obstruction. If they lose, they get crushed and the other player wins.
On June 23 2009, the U.S Copyright Office approved a patent application by Nintendo for an electronic, minigame-based implementation of Othello, whose description is very similar to Milky Way Delirium. Goro Abe, Kyoko Watanabe and Ryutaro Takahashi (all credited as designers on Mega Party Game$) are listed as the inventors.
