Ooooo, showing my age here! Mum & Dad owned an Atari 2600, so that was my first taste in gaming, followed by the 7800...
First console I would consider mine was the NES, as that was a birthday present: the first console I ever actually bought was a SNES, which I got on UK release day with the money I earned part time in between college (yep, I'm that old lol!)
