A relative had one in the 90s, I would occasionally play it. They had Sonic and a few other side scrollers. I thought the colour graphics were cool compared to my Game Boy. But the Game Gear was always had to be plugged in due to the battery drain so it seemed a bit pointless as a handheld, especially when the same relative also had a Mega Drive. 🤷

It’s a handheld I’d like to revisit some day if I come across one cheap.
