Monopoly 64 in short is nothing special. The game is a port of the original board game to the Nintendo 64. Monopoly 64 makes use of 3D graphics to represent the board. It also takes a step in allowing the player to play against computer controlled tokens, and also allowing players to modify the rules to their own choosing.
Monopoly 64 is probably the least likely game we expected to see a texture pack for, however there a user went about replacing some of the textures with higher resolution alternatives.
