We've all played video games where some characters from a series makes a crossover with another (or maybe even more series.). But the only crossovers we've seen Sonic in are all with Mario (with an exception of SSBB and Superstars). A lot of other video game characters get a crossover with more than one video game character or series. The Mario and Sonic games are pretty shweet, but who knows? Maybe if Sonic crossovers with another character or series, it could probably be a pretty good game, possibly even BETTER than his games with Mario. What character or series would YOU like to see have a crossover with Sonic??? Comment as much as you like. This might get people some game ideas (hint hint).
