HOW MAKE GAME

Can you be more specific? What kind of game you want to make?

product version = game mod.
So do you intend to make a whole game by modding an existing unreal engine game like Ark or Robo Recall or Fortnite or Conan, etc?

As Shadowriver asked, the answers depend completely on what kind of game you are thinking of making, and one little detail can change the answers.
