The number of games released on Steam this year has already surpassed the complete number of releases in 2015. Around 1300 games have been added to the Steam library since June, when Steam Direct was launched, allowing developers to publish on Steam without having to wait for approval. If the tempo continues, we could expect to have more than 5000 games released on Steam in 2017 only!
Just put things in the right perspective – that means that 2017 would have produced more games than all the years from 2006 to 2014 combined. No wonder your library grows each day.
Can’t be sure if this is a good thing, since it means that basically Steam allows almost any type and quality of game to get released. It’s a great deal for unknown developers to sell their products, but at the same time makes it harder to get an audience, competing with a growing number of titles all the time.
All we can do is wish Steam good luck, and hope that among the thousands of games, at least a couple of dozens will be great gaming-experiences.
