Yes, I loved my classic Gameboy. I took it everywhere with me. I never got into the blue or colour screen or any of the Gameboy's that followed. It was all about this classic one for me.
Games wise, it was down to 3 games for me:
1) Battle City.
2) Super Mario
I never really played any other games, just because I loved these 3 games so darn much! Besides, I had more games on my SNES, which I used much more ;)
