That’s what they said, two free games per month for all of 2019. A number of devs have announced exclusivity deals with Epic (hooray for competition! /s); such is the case for Team Meat and I read Subnautica has an expandalone planned, so possibly maybe Unknown Worlds, too.
Seems reasonable at least some of the next games will be ‘back catalog’, so to speak, from the devs that have signed. Some of my guesses would include ABZU, Bastion, some(?) Sanctum game, Rebel Galaxy and so on.
While “sustainable” is not the word I would use, I don’t think they’ll be willing to drop the coin to have more releases like Subnautica.
But then again, Galyonkin says sales aren’t all they are cracked up to be, and what devs want/need is visibility, also Unknown Worlds had Subnautica inside a charity Humble for free, I’m now wondering if they even got much money out of the deal.
The Epic Game Store being currently barren, visibility is certainly something the few games that are there, can have a lot of, so I see why high profile games may choose to launch there (Coffee Stain even removed their upcoming title from Steam!), but the store needs to fill up in order to be useful for users, so competition for attention will increase over time. Valve has been criticized for opening the floodgates and not doing enough for discovery, but IMO people focus too much on that side of the equation, forgetting that attention is a finite, delicate resource nevertheless.
Concerning the e-mail harvesting opt-out, it appears that is one of the features devs really wanted (implementation notwithstanding), as claimed by Galyonkin. Some interesting tidbits can be found in this Kotaku piece:
I don’t know, there are some things I don’t much like the sound of, so guess I’ll be sitting on the fence. Good or bad, Valve are a known quantity. This may be a good time for starting a Steam alternative, though, since there’s been mounting pressure against Valve from the press and user community, and certainly some discontent among devs is a thing, too. Epic has some good cards in their deck, that’s for sure… so grab a seat.
