I was 4 years late to the party (family got it in 1981) but I loved that there were well over 100 game variations of COMBAT. Not a great game but not terrible but ASTEROIDS really caught my attention!
I'll be 43 in October, so I was just a little too young to appreciate the VCS (as it was called when it was new) at the time, but I got the 2600 very early on, circa 1980 or 1981. Nearly 40 years of entertainment, and I still own a bunch of 2600s today.
