Haha, oh man. The Gameboy was pretty confined in its technology, but its biggest flaw was the lack of backlighting. You couldn't play the damn thing in the dark, outside in natural light, or basically anywhere other than directly under a lamp. I remember my parents bought a ridiculous and unwieldy little "kit" that I attached to my Gameboy to give it light, increased sound, and a little magnifying glass to see the screen better. If you could get around that, the games were actually highly enjoyable. I got loads of entertainment from the Mario games released on OG Gameboy.
