&gt; Three-Day Opening Weekend over $550 Million in Worldwide Sales; Is the Biggest Entertainment Launch of 2015, beating Jurassic World<p>I think this will be overshadowed by Fallout 4 <i>next week</i>.<p>According to Steam there were ~500k people playing simultanously (new record, beating GTA V). Given the <i>huge</i> amount of people that are <i>still</i> waiting for delivery of their copy, plus many people who start playing on the weekend (because of adult stuff during week days), plus high amounts of players who bought it for PS4&#x2F;XO... My naive miscalculation results in 10-20 million players, which results in &gt;1 billion dollars.<p>On the other side, my hobby-coding and other social activities stopped completely since tuesday night. I admit being a Fallout fanboy, so this is heavily biased.
