I’m just documenting the general approach I’ve found works for Unreal development.
If you’d prefer another approach, there’s Unity, Godot, Lumberyard, and many other engines, as well as the option of rolling your own.
Trying to go into Unreal without understanding what that really means, is a recipe for failure, so if you don’t want to own delivery of features yourself, you owe it to yourself to outsource that somewhere else.
