The original Game Boy had a rather poor screen that could manage 160×144 with about 4 levels of grayscale. The new screen needed to encompass this but with as small a physical size as possible.

The Game Boy remains the crown jewel not only of Nintendo's handhelds, but all on-the-go platforms that have ever released.

The original Game Boy changed the face of gaming ... One of the things I love about it is that it’s the same size as the iPhone and Apple Watch pieces, which means that it’ll look right ...
