Well, I like gog.com a lot it's full of free game it's cheap, there is a good community.
But like Steam it's fully digital, so what happen if one (very sad) day gog.com has to close.
I know we can store game on our PC. But I buy digital game, so this way I don't have to keep a DVD or ISO on my PC. So I was wondering, will there be any financial compensation or other things. Because our HDD are not immortals, and so one day we will lost our games and will be unable to redownload them.
I hope I don't afraid people by posting this. Come on guys you can buy games here gog.com never felt better than now, and had, I think, still a lot of great days to come.

You can save the game to CD or DVD. Then re-install it any time you want.
Once re-installed, you do not need the disk to play.

Just be aware that just like hard drives CD and DVD media don't last that long.

Hard drives 3-5 years
off the shelf CD/DVD 5-10 years


Any permanent backup method involves multiple backups and move to new media periodically. If you trust all of your data to one place in the "cloud" then you will lose your data.

If you buy a CD from a store, do you expect the store to give you a refund if it stops working in 15 years?

Well when you buy a CD, you can claim to the editor to give you an other CD if you ask before 90 days, after you'll had to pay 20$. But there is no limit time, so you can ask 100 years later if you want.

If GOG.com closes?

Mass riots in the streets. The Earth shall burn and crumble!

If GOG.com closes you lose access to your account and you won't be able to redownload your games. As any other digital store the EULA warns you about the termination of the service because nothing lasts forever and they have to cover themselves in case of bankruptcy. Read the subscriber's agreement.
You won't receive financial compensation, they'll probably give you a heads up before they close so you can backup your games though.

If your data is important to you, you should keep multiple copies at different locations (inside the cupboard and on the desk doesn't count as multiple locations, neither does two folders on the same drive, at your place and at a friends place probably does), no matter how the data was acquired. This applies not only to GOG games, but also to personal files like photos you'd prefer not to loose.

Yes, I'm absolutely terrible at following my own advice, why'd you ask?

If GOG shuts down we'll probably get a bit of warning so that we can ensure that we've downloaded the installers to all of our games (provided you haven't done that already). Keeping track of those installers and backing them up is all up to you after that.

Just like MP3s you need to keep a stable backup of your GOG purchases. The easiest way to do this is to keep them on your local PC as well as an external drive. If one drive dies, replace it and copy the files over again.

Well thanks guys I knew I get plenty of response like this. maybe I should give a warming, more details.
I'm asking what gog.com will do if this happen. not me.
I'm pretty sure they'll annouce their server shutdowns like 1 or 2 months before. But is that all ? I know it sounds cruel to ask more, when an enterprise close but I have to ask. It's my money too. Hope you understand.

Pretty much this. Though as long as GOG is still around, keeping 1 or 2 backup copies should be enough. But if GOG ever closes, I'll be sending backup copies of my stuff in space and at the bottom of the ocean, just in case. Also, I'll probably be very angry and plotting the destruction of the world, hence sending backup copies in space.

GOG probably aren't gonna do anything besides telling you to "backup your games". Hopefully in advance =P

Propably I'll have to buy bigger hard drive. And keep gog-installers in other smaller one.
Hopefully gog will come bigger and better. This is a good place.
Or propably I should learn how to burn 10 gb witcher 2 in a disc or few.

The advice everyone is giving you is exactly what will happen. GOG will do nothing more than warn us ahead of time (hopefully), but that's it. It is up to you to secure your data and there is no reason for GOG to compensate you if you don't bother to do that.
