Problem
The steps to getting started, and any proceeding steps, are too scattered;
it's difficult to locate, concretely, what to do first and so on for anyone new to this creator's world
-- specifically, for anyone wanting to make a First Person Shooter.

I believe it to be best if an outlet for creation is streamlined and easier to access.
And I wish, if this thread is successful, that other threads like this one be made for other genres.

Solution
Below, I would like to list a tree of steps (videos, other threads, etc)
so that the transition from beginner to intermediate can become a little less confusing.
To "get the ball rolling" is the main goal.

In order to do this, I need your help in gathering a collection of information.
It would be most welcome if anyone (who remembers what they read or viewed to first get started) could post their starter material, here.

I Will Update This Thread With Your Material
