A fun party game to play with Mario and friends. - Game Title: Mario Party 9 - Platform: Wii - CERO Rating: A - Disc Condition: Good - Included Items: Instruction manual, some may be missing This is a set of 4. I don't have a Wii, so I can't confirm if it works. If it doesn't work, please consider it as junk! I've had it sitting around unused for a long time. Price negotiations are welcome!! The package is dirty, but the CDs have scratches, but are relatively clean. Thank you for looking.
