Since I feel this forum is/should be more than just a godot engine help desk and rather a game development community in general I thought its a good idea to share and discuss postmortems we have watched/read and found interesting and helpful. I'll start with the Horizon zero dawn Postmortem from GDC below.
For the conception and pre-production I fount the explanation of starting with a wide scope and working towards a more narrow scope interesting, however it's not like this is a new and revolutionary idea.
Talking about production, my primary takeaway from this one was that it might be best to start developing your game from end and work towards the beginning. Each time you take a step further back and add some new elements to the game play you also go over the later parts of the game and see how you can integrate them to the end game. If you can't then it probably either doesn't fit your game or the endgame is not designed sufficiently well. Also this way you can tutorialize the early game accounting for everything that will be in the later game.
