Maybe one of these, cause I have played thousands:

Popeye, Castlevania, Contra, Scorch, Minesweeper etc...
My memory doesn't back up well...

edit: oh yeah - maybe it was Paperboy, Lode Runner, Prince of Persia... :D

I'm not entirely sure, but I do recall playing Space Wars (the Cinematronic upright cabinet version, if it matters) with my dad at our local airport in Charleston, SC. I couldn't have been more than four years old at the time. I also recall playing Pong on a console at my cousin's house, which would have been right around the same time (1978 or so). I don't know which came first.

Ummm, let's see... Doom? I happened to find it on my dad's computer :twisted: Or then it was Alladdin, Lion King or something else... I've played games nearly my whole life (13 and a half) so it's hard to keep track... Or then it was one of 'em clicking games that when you click something something pops out of there..

My first game was Ladder. It was some early kind of Lode Runner back in the 80ies on a Schneider PC System with a green, perhaps 10inch monitor. It was the computer of my best friends elder brother and we were very happy to be allowed to play this fabulous game. It had no real graphics. Everything was made of letters.

Pong... This must've been way back in 1984 (I was 3-4 years old).

Chuckie Egg for the MSX 32K. I was so little I don't even remember, but my dad tells me so and kept the tape as a souvenir.

Super Mario Bros 3 and I beat it within a month without whistles. I got so excited when i finally beat it. :D

Mario Bros 3 or Zelda, could have been some atari game too.

Frogger, if I remember correctly.
I also played things like Paperboy, Alley Cat and Paratrooper, but I'm reasonably sure the first game I ever played was Frogger.

First one? A Scott Adams' graphical adventure for the Apple II--I think it was Adventureland. A friend of mine had purchased the computer for writing, and they got the game, then showed it to a bunch of us (we were all writers). This was in 1978, I think, and we sat around and made suitably sarcastic remarks about the simplistic plot and choices, along with more impressed comments about the ability to move in different directions with appropriate graphics.

For those who remember those Adams game, I should mention that I was in touch with him about three years ago. He's once again creating graphics adventures, but for a small market that likes his retro style.
