Its impossible to relate now to then...
For one third gen I was seven and the video games although simple could be totally mastered and were designed to play endlessly.
Pitfall. Space Invaders. Asteroids.
Now the games are immersive but I am less readily impressed. Also the improvement in graphics removes a lot of the imagination required to make certain titles come to life.
Basically I grew up. Maybe a young kid playing today will have the same amount of joy from playing his first video games as I did in the seventies.
For me. Time is short now a days and I have to take my gaming in snatches.
