I'm currently going back to the origins of video game industry and making my own Atari 2600 homebrew game. If I had a time machine, I will immediately jump back at the beginning of my favorite decade, which is, of course, the 80's and go work for Atari.
If you want to understand the true origins of the game industry's unique production culture, you must study the early years of Atari. All the current industry "patterns" emerged from those original gamedev gurus. By making my own Atari 2600 game from scratch, it's giving me the chance to at least experience how video games were originally made and maybe give me some new insights.
