My brother wrote the games, and I played them. I remember playing his tetris for hours on end because he wasn't aware that speed had to increase (he'd only glimpsed the original briefly).
Ah, I'm with you anyway, I did indeed spend hours and hours and hours, at one point in my life, gaming away .. for me it was Descent2 and Warcraft2, the good ol' 90's, and well .. it didn't last long. I realized I was better off writing code than running someone elses. ;)
