But to many of the longtime fans, the debate still has not been totally resolved. In truth, the one thing that the fans still TRULY long for is a huge, platforming adventure that lets the two heroes and their friends, possibly, visit each other's worlds, duke it out, and ultimately team up to bring down some greater evil. However, as has been proven before, this request, though seemingly simple, is a lot harder to bring to fruition than it seems. After all, both franchises have always been both known best for their platforming, right? True, but the problem comes in when you consider how radically different the two playstyles between a Mario and Sonic game are. Osamu Ohashi discussed this in great detail, but what he said can be summed up to this:

Then, some time ago, SEGA secured a license to create games based on the Olympics. At that point I came up with the idea of having Mario and Sonic compete with each other in the Olympic games setting. We proposed that idea to Nintendo and they were really positive and interested in the idea, so that is where we started building it into a concrete game proposal.
And now we have a hedgehog and a plumber competing in friendly Olympic-themed competitions. Yup.
This issue seems to be a rather stumping one, and it can be really hard to discern what measures would actually have to be taken in order to create a quality Mario & Sonic adventure. Of course, the guys over here at Retro are all incredibly smart, and I'm quite certain we could come up with some solution. I myself have an idea that I consider to be quite good and I believe covers all the bases that would be required to be present and agreed upon by both Nintendo and SEGA, but I'll stay quiet unless asked for the time being. As of right now, I'd like to hear from you guys, and what your opinions/thoughts/solutions on the matter would be.
