What a weird world we live in. Men turning into women. Animals coming up missing. And Sonic the Hedgehog on Nintendo systems. Now it's time for Sonic and Mario to see who's the better 16-bit adventurer. Play through all the Mario adventures while spinning to collect coins and beat up on Bowser. Or, you can take Mario and Luigi through a series of fast paces, action packed Sonic levels. We've added some pictures below. Perhaps we'll see the Japanese version of this game ported from the Neo Geo Pocket Color to the Game Boy Advance when it comes over here. Maybe not, though.
