Sumo Digital did intend to put Mario in the first game, but Sega decided to only have Mario and Sonic crossovers at the Olympic. However, that decision contradicted with Super Smash Bros. Now that Sonic is in two Smash games, the cross-contamination isn't a good excuse anymore because Sonic has seen so much Nintendo stuff by being in Brawl and confirmed for Smash 4. It's time for Mario to see Sonic's Sega friends. The only SEGA content that Mario has seen is from the Sonic series. By being in Smash, Sonic has met characters like Link, Kirby, Pikachu, Samus Aran, Fox McCloud, Pit, Captain Olimar & Pikmin, Toon Link, Marth, Zelda, and King Dedede. He has been in many Nintendo locations like the Pokémon Stadium, Spear Pillar from the Sinnoh region of the Pokémon world. He's seen assist trophies of many obscure Nintendo characters like Starfy and Little Mac from Punch-Out. He has seen a whole bunch of Pokémon and has even thrown Poké Balls. Sonic has seen so much of Nintendo in Brawl. Mario has only seen Sonic's universe. Putting Mario in Sonic & All-Stars would help even it out instead of making Sonic a spy.
