Every game I've purchased on Steam is backed up. To a single hard drive. And should, some day, Valve look as if it were in dire straits, I'll be able take advantage of the fact that my backups are stand alone files which can simply be copied to preserve.
And until then you can rest easy in the knowledge that you have negated Steam's biggest selling point, not having to keep games locally, while accepting all the downsides.
How about you? How are your games backed up? Do you have back ups, since you had your nose turned up high enough to drown when it rains over the idea of cracks, I'm guessing no.
My games are 'backed up' on the physical media I bought them on. A single point of failure, yes, but one with a far longer lifespan that your option. I've lost over a terabyte of data over the last few years to HDD failures. I've never had a damaged disk.
And I get this 'backup' simply by buying - I pay and get something I can keep forever, whereas you pay and then have to make arrangements for when your 'online backup' inevitably disappears.
As for cracks, I crack all my games to remove the CD check (I don't have a problem with such legally questionable things, and I get something the pirates can't supply when I buy), though my games will work as purchased with minor inconvenience even if I somehow lose the cracks - whereas yours will simply cease to function.
You would prefer to pretend that in a decade you'll still be able to load those scratched CDs, that the scratches won't set off the SecureRom (or whatever DRM your game came with) disk check. That should YOUR six binders of games get stolen, the police will quickly and efficiently find the villain and return your property unharmed.
In a decade's time my CDs will still be unscratched, as my current decade-old CDs are now - I know how to look after them.
Perhaps they will get stolen. Perhaps my house will burn down. Physical backups aren't perfectly safe, I never said they were. But at least in those situations, something bad actually happened, some extraordinary circumstance, an unfortunate fact of life. Rather that than some decision by a company somewhere to remote-kill my games, when they would have continued to work just fine otherwise.
To take my games from me you must actually take them, or destroy them. Yours ask for permission to even run, and the developer can simply refuse.
And this is just part of what is wrong with Steam.
I can understand the average Joe Random embracing Steam, they aren't going to be playing the same games next year, let alone in ten years, so none of this concerns them. But you actually want to keep your games permanently, and understand that Steam is directly opposed to this, and your response is to accept Steam and go to extra effort to mitigate its issues. Interesting.
