For me it was Pong, my older brother got an Atari Telegame Pong Console for his Birthday and I ended up playing it more than him. He was not that much into video games. That sold me, from there it was Atarti 2600, NES, Sega Genesis, Super NES, PC games like Wolfenstein, Monkey Island, Grim Fandango, Doom, Unreal. Then I went on with PS1, Xbox, Xbox 360 and now PS4. I am 37 so yeah I have a long gaming history.
