Well, when Smash 4 comes out, it's two crossovers with the other characters. And I've heard rumors of a Zelda level DLC for Sonic Lost World. No matter how many crossovers with Sonic, Mario is still not a Sonic character. At the time of Sonic's creation, Nintendo and Sega were bitter rivals. Having them star together in one game was unthinkable until they appeared in the Olympics. We don't write details on the Mario series outside of the Olympics and Smash Bros. And if we were to put just the Sonic trophies and stickers in the gallery, that would be redundant since they are already listed in the main article.
