As no-one has yet done so, a link to Positech's blog on the Unity situation provides some interesting details from a developer perspective (responsible for the Democracy series, Gratuitous Space/Tank Battles, Redshirt and Big Pharma).
Positech.co.uk: A longer perspective on the unity pricing fiasco And now for loads of gratuitous follow-ups... ;)
CymTyr: There is absolutely no need for Steam to ever institute a server tax...
Well, how about the fact that the
Steam Agreement is actually
titled a "Subscriber Agreement"? That flags up the likelihood of regular payments from the get-go. Of course there is no "need" for it - but with over
120 million users, imposing a (say) $5/month fee would bring in an extra
$5.4 billion per year assuming a 75% takeup (and that's likely an underestimate given that those rejecting it could lose access to their games collection). Even
if Gabe was "saintly" enough to turn that sort of money down, he's not going to be running Valve forever - and just as Unity's change of policy seems to have been driven by an out-of-touch management, the same could happen for Valve or any other company.
CymTyr: What makes you think Gabe would be greedy enough to send people elsewhere?...The worst thing he's ever done is stand behind the 30% revenue share.
I think you've kind of answered your own question here.
amok: It isa little shaky, but legally they can. This is all i the licensing agreement
eric5h5: They absolutely legally can not, and it is not
See
here for a counter-example. Yes, it involves iTunes - but it shows that purchased virtual content can be withdrawn and has been going on for several years and has now resulted in class action lawsuits:
9to5mac.com: Another class action lawsuit over the risk of iTunes purchased content removal TheVerge.com: Apple lawsuit over "buy" and "rent" labels for digital content can continue, rules federal judge This class action seems to have been
largely dismissed due to lack of information provided by the plaintiffs. Unless someone can point to a result showing otherwise, this would seem to indicate (within the United States at least) that paid-for content can be withdrawn as long as the store/distributor mentions this possibility.
rtcvb32: ...i found The order of 12. 530Mb big, but i have it stored as 46Mb in a 7z file. Even recompressing as a zip (
so each file has it's own compression ratio data unrelated to others, weaker compression but still relevant) you can see a huge amount of... likely empty unused space. Why can't that unused space just get removed to reduce the game to say 100Mb? I don't know.
Compression is a trade-off between CPU and disk/SSD storage. Since most systems have storage capabilities in the terabyte range, why bother with compression if that results in noticeably higher CPU usage?
Now I would agree that Unity3D
is hideously inefficient, in the unreasonably high demands it puts on GPUs to render relatively straightforward graphics (like the fixed perspective used in Pillars of Eternity). But I don't think measuring the compressibility of Unity data is a good way to quantify that.
mdqp: Is there a list of which games here on GOG use Unity? Perhaps I should download the installers now, and make a list so I can check if they connect onlne, and block them if they do.
neumi5694: Here are some: House Party, Beat Saber, Death's Door, Pillars of Eternity, Superhot, Kerbal Space Program, Ghost of a Tale, Return Of The Obra Dinn, Cuphead, Hollow Knight, 99 Levels to Hell, FAR Lone Sails, My Friend Pedro
Dreamfall Chapters, Wasteland 2, Torment: Tides of Numenera - none of these require online connectivity though.
