If it's a platform where you can play oldschool games, that's cool I guess. But people already play em on emutators anyway so what's the point? If it's meant to be a serious console to go up against Microsoft, Sony and Nintendo... well... As much as I'd like to see it succeed, I'm pretty sure it would fail horribly and they'd have to close down. There's no way companies (other than some random indie developers) would make games for it. I mean just look at the wii and switch, all the big dogs are completely ignoring those cause it's a waste of resources to develop for those platforms. Besides, all the huge titles already have contracts with ms and sony..
I'm sorry, but I really don't see this going well for atari. Even if the console turned out to be amazing and more powerful than both xbox and playstation, people ain't gonna buy it cause they want to play on the consoles everyone else already use.
