Sonic has been in two Super Smash Bros. games. Wouldn't you think it is Mario's turn to be in a Sega All-Stars game? In fact Sumo Digital once considered Mario as a guest star of the Wii version of the first Sonic & Sega All-Stars Racing game, however SEGA rejected the idea because they didn't want to cross-contaminate the Mario & Sonic series. However, Sonic appeared in Brawl a couple years earlier and was confirmed for Super Smash Bros 4 last month. Sonic is so overexposed to Nintendo. Sonic met characters like Pikachu, Link, Kirby, Samus Aran, Captain Falcon, Fox McCloud, Mr. Game & Watch, Meta Knight, and other characters from major Nintendo games. However, all Mario knows of Sega is Team Sonic at the Olympics, which just had Sonic characters. If Sonic can be in two Nintendo All-Stars games, why can't Mario be in even one Sega All-Stars game? I mean he has his own kart from Mario Kart, and the transformations of his kart can be similar to Mario Kart 7. If Mario in the Sonic & All-Stars Racing series would cross-contaminate the Mario & Sonic series, the Super Smash Bros. series already did twice.
