[quote name='choral_music']It's not Steam that would die, but rather a licensing agreement which would result in delistings.
It's happened to almighty Amazon's Kindle marketplace. Hell, people plugged in their Kindles and it erased some of their books. It happens all the time on Apple's app store. It can happen here.
So, yes, the fears are rational.[/QUOTE]
Actually, Steam games they delist are no longer available for purchase, but remain available for re-download. There's actually a list of them on the Steam forums if you care to look. See, your Steam purchase entitles you to a license to use said game, so even if they can't sell any more licenses, they still store your purchase and allow you to redownload it when needed.
