Ahhhh how are people already streaming fallout 4!?!
Early copies were brought in, some people already got their hands on their copies because some stores let them be picked up early. For example, GameStop is doing a midnight release today. Steam is doing pre-load for pre-purchases on Steam. And some people likewise are being assholes and spoiling the game's ending already. Which is
ridiculous as the game is not even officially released yet. Some people..
Oh and YouTubers usually make use of the early opportunities before them.
