One of the causes of more games in Steam is thanks to the Steam Direct program that replaces Steam Greenlight.
The program allows developers to introduce the game directly without having to go through the selection process by Steam.
Steam Direct itself has donated more than 1,300 games since June and if that number can be maintained, then Steam will certainly be able to release more than 5,000 games this year.
5,000 games is not a small amount. In Steam's history, the number is equal to the number of games released from 2006 to 2014. However, having many games will also present certain consequences. One of them for developers is the more difficult to bring the game that can attract attention because more and more competitors.
