Mine was the original DOOM on an old computer back when I was about 3 or so. It belonged to my Dad and me and my sister were pretty young at the time and sometimes he'd load it up for us to play. I didn' really understand that I was shooting at demons and dogs (At least I thought they were dogs back then), I didn't even know I was on mars (So take that claims that violent video games make violent kids). Ahh we used to have such fun (My lifelong love of more hardcore gaming started there, my lifelong love of more casual gaming started around the same time on an old flash games website called Alfie). My first console experience was on my former good friend Matts old playstation one with games like Spyro the dragon. But the oldest video game I've ever played, a year or so ago we were in Melbourne (To see some kind of art exhibit) Now I'm not really for big, noisy, sprawling cities like Melbourne so to cheer me up my Dad took me out one night to a thing they had on called Game on I do believe (I found out recently that Yahtzee had been there a few days before or after like signing autographs or something, NOOOOOOO). It was such a fun night out, it was just all these classic consoles and games hooked up to tv sets with little descriptions next to each one, they also had arcade and handheld games, also gaming props like a Max Payne jacket replica and a little theatre were they were playing classic machinimas like the ballad of black-mesa and red vs blue. It was there that I played pitfall on the atari-2600.
