Atari 2600, 5200 and 7800 represent!
The 2600 and 5200 were the first consoles I ever played, both owned by my cousins, and then the 7800 became my first ever very own console.
I was very happy with my Atari 7800 even though my friends all had NES. When I finaly got an NES I think I apreatiated it more because I didn't take it's graphics for granted. The 7800 and it's wonky controller will always have a special place in my heart. I think I used it more for Atari 2600 games though. My friends and I would use it for Pong even when the SNES and Genesis were all the rage. Pong is timeless.
