82: Sega Game Gear
Yeah I used to own one, I only had one game for it, Bart vs The Space Mutants, which itself was an impossibly difficult game with some of the worst controls of all time. Now imagine playing it on a system that used 6 batteries and drained them in only a few hours.
F*cking fustrating is an understatement.
This problem prevented Game Gear from outselling the Game Boy, a system that didn't even have any color.
So yeah, even as a little kid I knew Game Gear was a bunch of bullsh*t, it had some decent games but the insanely short battery life made them practically unplayable (thank god for emulators), I ended up trading it and getting a Super Nintendo, smart investment.
