With how poorly received the Game Gear was, I feel reluctant over more mini-consoles.
What? Game Gear Micro wasn't poorly received, it's sold very well.
If you didn't see them in your local gamestores because those handhelds were only sold in Japan and Asia.
It was never released in western market and it would be too small anyway for average western people's hand since it's 92% smaller than the original.
With the technology we have now, it would've probably been cost-efficient if they just made full-size Game Gears but with revised electronics in comparison to the Leapster or Game Boy Advance.
While there's hardly any hard-copies of Game Gear games in circulation these days, if you just so happen to come across one, at least you'd have a more practical Game Gear for it.
As for the Micro Game Gear libraries, well if Nintendo can fit a 32GB game onto a cartridge the size of a fifty pence coin, then Sega can fit a library of games into a cartridge that can fit in one's palm.
Actually it's still not cost-efficient.
Yosuke Okunari has said that producing them are still costly.
Not just the hardware alone, but also with the games licensing things.
Besides consoles and handhelds were mostly sold at a loss and always planned to recoup via software sales.
If there were no new games for those consoles, it's still gonna be a loss for them.
Even if there are new games if they're not sold well enough to be a hit it's still gonna be a loss.
