My first approach to LCD games was in the mid 90s when I was a kid with Tiger portable consoles. I remember having one of Star Wars ep I, the console itself was a lightsaber and when you swim it the character (Obi-wan) attacks. For the Nintendo game and watch, I remember a friend of mine had a mini version of Dk jr, it was like a special edition.
The thing I love about the LCD games is the design limitations. Jumpei put a good basis to design a game, in my opinion in LCD games the flow is very important, and they achieve a good flow of difficulty on those G&W that holds up very well.
