My first video game sys was some Atari with built in games, but I can't remember the model. I was so long ago I can remember only Tom Boy game. I didn't like it though and I got rid of it quick...
My real pleasure was the NES, but it wasn't exactly a NES. It was something like "Family Game" - some kind of NES Chineese knock off with built in games (thosands versions of mario, virtual pool, contra, lode runner, baloon fight, arabian nights, duck hunt, rockman 1, kung fu and some others). It looked totally different from the original NES but used compatible cartridges. The best thing was that the pirate cartridges contained like 8-10 different games for a low price - quite good bargain, eh?
