It was dead the second Nintendo announced they were done with them, as NES Classic and SNES Classic were the only two good ones ever made. Otherwise they have been cash grabs for crap quality hardware. Atari Flashback has been released 4-5 times and it has been every single time. Genesis Flashback has been even worse with garbage audio and terrible emulation every single time it has been released. And the controllers have been junk too. The Namco Blast machines have been horrible, advertising arcade games on the box and then being loaded with NES versions of the arcade games on the actual machines. Neo Geo Classic was stupid and the controller was crap. Commodore 64 Mini had a terrible game selection. And then Playstation Classic had a ridiculous price tag for horrible quality emulation.
Good riddance to the micro console if Nintendo is out of the picture. Nintendo is the only company who ever cared in the slightest about putting out a product people would enjoy using. And I still play the out of my SNES Classic because the controller is spot on and the emulation feels just like the real SNES (and with an NES Classic controller and dual booting into the NES Classic it feels like a real NES too). It's sad the NES/SNES Classic have been cancelled, because they're outstanding quality and worth every cent. If anyone is thinking about getting one do it ASAP because they're not going to be stocked again.
