javier0889: I never played Defender, but I forgot about this one
https://www.youtube.com/watch?v=1GCRYv4GlRQ (whoa, the loading screen brings back a lot of memories). Man, those cramps were a thing to consider, especially with all those third party joysticks...
On the other hand, watching these videos made me realize how little the basic concept of "video game" has changed over the years...
I never did play that game, but would have loved it as a kid :)
Was showing some videos to my daughter of old atari games and the main thing she was concerned with was the poor graphics LOL
You are right though, the premise of a "video game" has not changed much over the years, just the journey to get to the end and how it looks has ;-)
