And when nobody expected, November last year we finally got the announcement of the new Half-Life game. Half-Life: Alyx is coming this Monday, March 23, and its already generating enormous hype amongst fans. Some have suspected that the game will not be as popular as its predecessors, due to the fact that its a VR title, but they couldn't be more wrong.
In the months following the announcement, Valve Index VR supplies were "plundered" by fans at the rate so fast, that Valve couldn't meet with demand, and was out of stock for weeks.
Right now, day and a half before the release, PlayTracker Insight estimates that more than 300K people already own the game on Steam. Out of that number, around ~119 000 players got it by buying Valve Index VR (You get Alyx and other stuff free if you own Index).
If these numbers turn out to be accurate, it means that the game is already by far the best selling title in 2020 (up to this point), and surely it will be interesting to see if Valve will show us official numbers at some point.
