After being very sceptical about Steam for a long time (and still not agreeing with everything about it), I have come to appreciate the convenience of having a single platform for almost every game I buy these days. I have also begun buying many older titles for my collection, even though I already own them in some other form, just so I can have them all available at any time and place and not have to keep all the boxes and DVDs.
After investing hundreds of €s, I was wondering, if there is any kind of guarantee, that Steam won't simply go bankrupt and/or shut down all the servers or individual titles at some point in the future and erase my precious collection :/ I mean, it's not like GOG, where you can download everything you bought and store it on your hard drive, if they ever go out of business. There's no point in collecting, if I can't keep my stuff until I'm feeding the worms. Does the AGB cover this topic? Is Valve within their rights to declare all my "licenses" expired as they please?
