Mario & Sonic at the Olympic Games is a Nintendo DS sports game featuring the Mario and Sonic franchises in Olympic-style competition. The handheld version ties the crossover to the Beijing 2008 Olympic Games theme, bringing both character lineups into a shared event-based format.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Sports gameplay centers on Olympic events rather than a traditional platforming or adventure structure.
• Mario and Sonic appear together in the same title, pairing Nintendo and Sega mascot characters in a crossover format.
• Touch-screen handheld play gives the Nintendo DS version a different feel from console sports collections.
• The Olympic branding and event theme distinguish it from standard Mario sports or Sonic racing titles.

This release is part of the long-running Mario & Sonic Olympic Games crossover series, which continued with later entries themed around subsequent Olympic Games.
