You say this in jest, however what you don't realize...I can see it now, the Nintendo TV Game! Sega's been into that business too, y'know - releasing oldies in a "hook-me-up-to-a-tv-and-you're-set" format.
Of course it's just licensed third-party devices, but hey! Still a nice, quirky gadget to own. There's even ones shaped like Sonic's head - that must be hella uncomfortable to actually play on!
is that it already exists.
