Your first video game you ever played.

[Rushmeister]

Pong. 

At a Sears store in West Lafayette, Indiana.  Had to be about 1975.  The home video game idea seemed pretty cool at the time, but it wasn't enough to diminish my love of pinball. 

Correction:  I just remembered that I played a Midway Sea Raider game in the autumn of 1973.  Man, I can't believe I forgot about that game.  It's all rushing back to me now! It was at Shawnee Bend Resort at Lake of the Ozarks.  It was a super-cool game in its time, but I could make my quarters last longer in the pinball machines, so I only played it a couple times.
