Joe: In many games there is a theme of endless progress.
At the beginning you have very limited possibilities.
A small number of items, only a few simple tools, etc.
But by performing various actions you constantly improve your situation until you finally rule the world.
Joe: For example, you start with wood as the only reasonably available material, and you make everything from it, buildings, objects, tools.
Even things which wouldn't make much sense in real life. Like for example a wooden axe which you use to cut down trees.
Later you get access to more advanced materials.
Joe: But wood is a good material for many things.
Joe: Yes, but that's not the point.
