Whoops! Started reading these threads and quickly jumped to the last.
Some firsts are more memorable than others
.
There's no way I can recall it. However it wasn't on computer, probably was Nintendo. (I'm so old I didn't even see a computer from a distance til I was 15. Like early stoneage to some.)
The first game I can remember clearly was Escape from Monkey Island, quickly followed by Grim Fandango and GK (1,2&3).
