How to activate the game? (Red Dead Redemption 2)

First there was information that the game requires one-time Internet connection. After activation, the Internet can be completely shut down and the game will work fine. You can even turn off the game, turn on again and the game will still work without the Internet. But if you turn off the computer, next time once an Internet connection is required again.
Now stumbled upon the old, that in which the patch is changed once a network connection and activate the game, Internet more does not need. Many times you can rebulit computer and the game should run without the Internet.

How did all this actually work? Now to spend 2,500 rubles, I just can not bring myself to do it, but in the future, at a discount, you could buy.... provided that the Internet connection is required only once.
