I mean a bit of everything, people on the forum here are vary, and each one of them would like to hear more about one side rather than another. For instance, if you had a problem in running many AIs in the game, how did you solve it? Did you build a tool during the development (here is an example from the Unreal Blog) to speed up your development process? Maybe you had a particular pipeline to create a specific part of the world, or even you set up a very complex material for something and you can tell how you build it iteration after iteration. As a developer, I’m just more curious about these aspects, along with the game itself.
