In this DS adaptation of the Wii title, Sega and Nintendo's characters appear in the same game for the first time in history. At the same time, this title uses the official Beijing 2008 Olympic Games license and features the official venues and environments of the 2008 Olympic Games. Mario, Luigi, Peach, and friends go head to head with Sonic, Tails, Knuckles, and their group in a sports competition through various Olympic events. Each character has different sets of attributes; these attributes give certain characters a slight advantage over others in particular events.
