rampancy: Wait, what? What do you mean?
I mean that D2D was bought out by Gamefly. Instead of keeping D2D they're simply using D2D's user accounts instead and transferring those to Gamefly.
Not all games will be available for sale and not all games will remain in your account. That will start in January so now's a bad time to be making purchases from D2D, even if they're DRM-free.
Foxhack: 1: The installers are DRM-free. Buy, download, backup.
2: Was that comment because they were bought out by Gamefly?
Bought out and folded, yes. D2D won't be around anymore by the end of the year. They're transferring the accounts, but not all the games will be on Gamefly, so not all of your games will be in your account (maybe, you might get lucky).
So at this point in time it's risky making even a DRM-free purchase. If something goes wrong with the transaction then you won't have any time to sort that out. Especially not over the Christmas period.
