All businesses have costs -bandwidth, rent, wages, publicity, whatnot...- and like any store, the income they use to pay those wages comes directly from sales.

Or you know like every other store out there that relies on customers constantly buying new stuff but i guess that is too high thinking for millennials, rather mention a pyramide scheme that actually works completely different.

And gog won't "end", even in the questionable case that CD Projekt goes under, it will be bought out by another company that sees that there can be made money easily with it and they will just continue it.
In this day and age something like gog wouldn't simply vanish because of bankruptcy like some small-time brick & mortar store.

Considering CD Projekt made a profit of about 80 million euro in 2015, i kinda doubt they will go out of business any time soon and if they fall on hard times, all they have to do is puke out another Witcher which will sell like crazy as long as the hype machine works good enough.

OK, you're generally right. But do not confuse GOG with CD Projekt RED. They are the same group, indeed, but I don't think that anyone would ever decide to spend profits made on development just to keep GOG alive. GOG need to work for himself and it's correct what I've said - storage and support will be provided as long as new sales are fine.

GOG is not like any other store. In case of store you pay, take your product and go away. In case of services you're receiving some service as long as you pay.

GOG is different. You can buy 1000 games (yay, great customer, aren't you?) today and decide to download them every single day for the next century without paying a cent to GOG. In such case at some point they will get a loss from you as a customer.

Any business have ongoing expenses that they account for, and GOG is no different in that case. Rent for bandwidth and storage space from the provider(s) they use is something that they have already accounted for, and that provider's business is to provide storage and bandwidth (to simplify it a bit).

I don't know which CDN GOG uses for their game downloads, but regardless of whether it's Akamai, Amazon CloudFront, Cloudflare, or any other of several dozens, that's practically no more than a rent GOG pays for the service of hosting the downloads.

One or a rare few customers trying to do what you say will likely not even measure in the statistics for said providers considering the amounts of traffic they already serve.

The other reason I'm burning installers on discs is because of Comcast's imposed limitation of 1 TB a month (a policy enforced since last November for many states). If my HDD goes bad, I will have to redownload games from GOG. Restoring installers from DVDs to my new second HDD would be more quicker. Again, if my DVD goes bad, I can always redownload from GOG.

DVD will hold game installers that I downloaded. HDD will hold updated game installers.

It's great to know that GOG will always be around for a long time. I will still buy more games from GOG.

As long as enough people buy games from GOG they'll survive.

Every time I buy a new game I store it on my external drive, it's easy to end up procrastinating otherwise.

To know the future is to be trapped by it.

I keep backups of my installers. And then I mirror the backups. It helps me sleep well at night.

I hope you don't mind, but I'm getting this as a forearm script tattoo in cursive font.

I believe that's a quote (or paraphrase) from Dune.

I doubt very much that GOG will close anytime soon, but it's a pretty safe bet that it won't be long before it's a client-mandatory, micro-transaction infested haven of sewage.

All they want is to be Steam, never realizing that Steam is already Steam and nobody needs another one.

Still getting it as a tat.

It was either that or We are GR00T as a neck tat.

Close enough. It's a line from the Children of Dune miniseries actually.

Yes, but isn't that quite common for quite a lot of businesses?

The good news is that new potential future GOG customers are born every day (who will have to start buying their games from scratch), and new games that GOG can sell are also being made constantly. So in that sense there are no worries.

There would indeed be a worry if people stopped breeding, and if new games stopped being made. But that is not the case for now.

Does anyone just copy their game folders to another GOG folder on another PC when they wanna play it on another PC? Thats how I do it.

I think you may find this helpful my friend:

I haven't used this script myself but I've heard good things. And like others have said, get an external hard drive.
