Monopoly was a video game version of the board game of the same name, licenced and produced for the Nintendo Entertainment System. The game played by the same rules as the standard board game, and allowed for single, or multiplayer games. When single player games were chosen, the game console would generate game bots with (at least for the time) fairly sophisticated A.I.. One of the lesser liked features of the game was the nessesity to play exactly in the style programmed into the game. This could be slightly different than the various "house rules" that many homes employ, and could cause problems. An especially problematic feature was the mandatory auctioning of un-bought properties, that led to rich players having a better run of the board.
