Sonic Team head Takashi Iizuka says he would love every Sonic game to be available on modern consoles, but thinks the effort involved would be better spent on new titles.
In case you weren't aware, there's a whole lot of Sonic games out there. Since 1991, there's been as many mainline console games as the entirety of Mario's mainline console and handheld games (that's with a six-year head start). But unlike Mario, where three of the New Super Mario Bros games and 3D Land are the extent of what you cannot play on the Switch consoles right now, there are a lot of Sonic Games that are simply unavailable on modern platforms.
