Does Wii Fit Come with a CD or Disc?

Wii Fit comes on a Wii Optical Disc (DVD-based), not a CD.

• Format: 12 cm Wii Optical Disc (single-layer, 4.7 GB) — same as all Wii games.
• No Installation: Wii runs games directly from disc; no install to internal memory required.
• Wii Balance Board: Bundled with the game; syncs wirelessly via Bluetooth.

Insert the disc into the Wii's slot-loading drive, sync the Balance Board, and play. No CD involved.
