In the second half of the year, several new offers and sales will be made available on Steam. In fact, dates for the next set of offers have already been determined, and they will be those associated with the "Festival of Digital Table Games 2021," which will take place from October 21 to October 25.
Valve has already begun accepting developer registrations, thereby officially confirming the date on which the registrations will open.
Following these offers, it is expected that the Halloween offers, which will include a large number of additional games, will expire, roughly between October 28 and November 1. The spring sales could take place from November 24 to November 30, and the summer sales could take place from December 22 to January 5. It is important to note that none of these release dates have been confirmed by Valve and are merely predictions.
One more interesting event that will be taking place on Steam is the upcoming Steam Next Fest, which will take place from October 1 to 7, during which we will be able to try demos of multiple indie games that have recently been released or are about to be released, so we recommend that you keep an eye out for news regarding said event.
