Time4Tea: It's hard to say what the future will hold for DRM-free over the next 20 years and many of the posts here seem quite negative. If we continue to see game servers being taken down, rendering games unplayable, then DRM-free might conceivably see increasing support.
Bear in mind, for the '80s/90s generation' (those who grew up in the 80s/90s) - most of the PC games they played as they were growing up
are still playable today, because DRM wasn't a thing. For the current generation, growing up in the 2000s/2010s, there is a strong chance that
most of the games they are growing up playing
won't be available in 20 years' time, because of the DRM. When they come to realize that - that the games they enjoyed in their youth have been taken away from them, that they are being denied their nostalgic fix - there might well be a reckoning.
Really? The games from 2000, 90`s and even 80`s were sold without any sort of DRM? What such happy days!
