Damn that's harsh. I grew up in a world where there was no such thing as handhelds. There were Tiger Electronics black and white LCD "games" but nothing like an actual handheld game system.
First time I saw a Lynx my mind was blown. I saved up every penny as a little kid to get one, used.
Gamegear came later, and again it blew mind. I do remember how it ate batteries.
Holy shit core memory unlocked. I don't think I ever got past like stage 3 of sonic because that thing DEVOURED batteries, and it was like a full set of 6 AA's, too. Felt like it was cheaper to go to the arcade. Worst console I ever owned!
I was the Nintendo dude in my friends group and my best friend was the Sega dude. So while we had fun back and forths we both got to experience both consoles pretty well. I remember being so happy when my friend got the wall adapter for his game gear lol
