I also have this. I hade it as a kid, but after growing up my parents sold it but few years ago I bought a new one from internet auction. This is the one and only console game, I don't want any Nintendo Wiis or XBoxes, this old Nintendo NES has the best games too! So far I've got only Super Mario Bros and Bubble Bobble. I definalitely still need at least Tetris and Super Mario 3.
I also try to find the three handhelds from my childhood too. One was Donkey Kong in the orange handheld, but there was also one blue and then this one black-white spaceship game my dad bought me from business trip.
