When I was still crawling, I crept up to the 2nd floor and found someone playing Oregon Trail. That is my first memory of videogames.

Many years later I received a SNES for X-mas, which came bundled with Super Mario All-Stars+World. I consider that my true entry into gaming. Good times.

"32 in 1 Game Cartridge" for the Atari 2600. Had it as long as I can remember. When I was three years old we got an Amiga 500. According to my Dad our first game for that one was North & South.

i remember that one i

i bought an atari 2600 on a fleamarker when i was 12...ish and that came with it

Pong, in the 70s - friend of the family
Late 70s my friend had an Atari 2600 - Pac Man, Spy Hunter, E.T.
Later in school another friend had a different system - Coleco? - on which we played Burger Time
Somebody in grade school had two of those mini arcade games - Galaga and Donkey Kong
At the arcades in the 80s - Centipede, Galaga
In '86 or '87 I think, we got an Apple II e. On which I discovered Trinity the text game and Scarab of Ra - two of my enduring favorites. At the same time my friend had the Ultima games - which ones, which system I don't know.

mario and stinger for the nes

My first computer game was probably the "Find the Happy Face" game my Dad wrote for the TRS-80. Late '70s.

There would be several faces on the screen and I had to pick which one was happy. At least that's how I think it worked... I was probably two or three at the time.

The original Tetris on a IBM 286 or 386 in the late 1980's... maybe? Could also have been Solitaire or Alley Cat, but it probably was Tetris.

Played: Prince of Persia 1 on Mac
Owned: F/A-18 Hornet 1.0, on Mac too. Still have the disks somewhere. Two 3.5" disks if i remember right. The next update had 4 already.

Played: Kaiser and Archon on the C64
Owned: Tetris, Super Mario Land and Gargoyle's Quest on the Game Boy

I'm not sure, I was very young.
I think it was a game on my fathers computer, something about Christmas, with various mini-games.

Probably Sonic the Hedgehog 2 for the Sega Mega Drive. I think I was around 3.

My very first game we owned and I played was Quake, on PC. As I recall, the biggest progress I made was passing through the first door in the very first level. I killed only first two monsters. I did it over and over again. Every day I would play Quake like this. And I got real good at this! There was hardly anyone better than me, who could pass the first small room :P

But all good things come to an end... My pops deleted this insanely fun game after weeks of warnings and sayings "Go, learn something useful, you... Good boy". My heart was broken. MS Paint became my friend. And when I was losing hope of getting any game at all, I received Wolfenstein Return to Castle. But that is another story...

"What was your first game? What platform was it on? What year was it? How old were you?"

I assume you mean first video game played.

Pong.
Pong console.
Probably 1978.
Presumably 12.

My very first game I owned was a Superman game for the Commodore 64 on cassette tape but I don't remember what the exact title was other than it was a game I purchased along with the system - and what a great system it was. The year was 1987 and I was 10 years old.
