At first I thought this was a good idea. It's still interesting and cute and all. But from a viability standpoint, I don't know. The influx of retro games in the past few years is thanks to apps and digital distribution where there aren't as many barriers for independent developers to make games, especially the barrier of having spend the money to produce physical media, like discs. Cartridges are even more expensive, so to now have to expect to produce them, would they?
And if games are also available on other platforms, and later get updates on those other versions, this machine that brags about not having to do updates, well, they're going to have inferior versions of these games. It's going to need a lot of exclusive games (as with any console, really).
It's clear they don't like patches and the whole thing about having a complete game in physical media. But there are advances in the past few years it would be hard to regress from...back to wired controllers, gah.
And if people want to relive retro games, there are plenty of opportunities to get old consoles in good condition that already have a proven library, and the games that likely make up those very memories.
I still like the idea, I just honestly don't think it'll go too well. Despite this "Negative Nelson" post part of me wishes to see it have some success.
