What I find interesting about this video is that the game was developed by a small but highly professional team.

Yes, the game development industry wasn’t nearly as complex as it is today. You could probably say that making and releasing a good game was easier back then. But these people created a legend precisely because they were professionals. Of course, DOOM wasn’t their first game. There was a time when the team was making a game every month. What I like most about this video is the sense of creativity — and the feeling that these people simply loved making games.
