Every once in a while, miraculous events can occur. A miracle child is born, a hidden gem of a Movie/Book/TV Show/Video Game is discovered, and maybe, just maybe, if the stars line up just right, and someone does a special dance, Valve will reveal a new game. Well, that day has come, and it is called Artifact, a....... game that literally no one wanted: a DOTA themed Hearthstone type of Card Game.
Yes, Valve is making a (more than likely) Free-To-Play card game, that is obviously little more than a cash grab given how more AAA devs are starting to get in on that market, namely with Bethesda and CD Project Red following Blizzard's Hearthstone. Valve unveiled the game and it's 2018 release "window" (although that's Valve time) at the International, their DOTA 2 tournament. The reaction to it? Well, imagine an entire audience of people watching one of their most anticipated events of the and then suddenly getting disappointed by learning that the company hosting the tournament, while taking a 30% cut off all Store purchases and leaving in some clearly exploitative systems for cash grabs from asset flipping and market place transactions, is making a low budget game that no one wanted or asked for and is clearly a cash grab instead of making a new sequel to literally ANY OF THEIR OTHER IPS! That sound that you imagined is more than likely no where near the real thing.
As per, the internet salt train has gotten chugging along, and I'll leave this comment from the reveal trailer to give you even more disappointment (although not entirely accurate):
Half Life 3 died for this.
