russellskanne: The game has no DRM and works fine offline. Since it solely Single Player, you should not allow outgoing connections via firewall anyway.
Just what we needed to hear. There's a review posted by what looks like an account made just to make this one review, The review is simply titled "DRM" and the user posting it is "DRM-Watch" - a user who seems to own 0 games and has only posted 1 review. That review has some exerts from Sony's EULA, which there is a link to right on the game's store page. The thing that catches my eye is the part about the internet connection being required for some features.
If those features are cloud saves, then duh. Of course.
But if those features were like just being able to play the 2nd half of the game, that'd be a problem.
And thanks to you, it looks like we've got someone who's really tried it and it's fine. Firewall it off and you miss nothing meaningful.
mistycoven: The data collection is the same as in Horizon Zero Dawn. Your choices are full and limited, no opt-out. You can block the game with your firewall, but bear in mind that the game connects to 127.0.0.1 (localhost) in order to facilitate achievements, so blocking all traffic will also prevent achievements from unlocking.
Hirako__: Interesting. Is there any way around that so the achievements can still work ? I read yesterday in another thread about the incoming God of War that such block affects also cloud saves - is that true ? I just tried myself with Fallout NV after blocking it and cloud saves were working but the achievements for another game did not so I wonder how these 2 are handled differently. Thankfully Days Gone does have its own in game Trophies( from the Playstation that it comes from) so you dont really need achievements but I find it sad that on steam blocking the exe does not affect the steam achievements from what I read - its only here...
Yes, local firewalls can allow a given program to connect to certain hosts (ie, localhost / 127.0.0.1 (and technically 127.anyhingelse)) and also block those same programs from connecting to anything else. To do this you need to actually make rules, so if you're asking this question, you've got some things to learn, but learning that stuff is kinda fun and fascinating and just dead useful IMHO.
The Windows firewall can do this. There are others out there too that are ultimately a little easier to use. I like Comodo's Firewall that comes with whatever they call their internet security package. It's free, and I opt out of everything else they offer with it - their web browser, DNS service, anti-virus etc. AFAIK those are fine products but I don't have need for myself and like to keep things lean. Probably some other firewalls out there now, but way back years ago when I was looking for a Windows firewall to replace like Tiny Personal Firewall and ZoneAlarm, that was about the best option I could find. Comodo enables a lot of extra stuff by default in their firewall these days, just look to turn all that off and look to enable all the advanced options. Oh and download the offline installer their devs post to their forum.
