Nintendo is NOT a third-party developer. Hotel Mario is an exception, but that was made by ANOTHER third-party developer. So, if you want a Mario game, get a Nintendo system. For Sonic, they had games on Sega's consoles until they discontinued the Dreamcast and repositioned themselves as a third-party developer, so ANY console can have Sonic.
