I've used D2D to download Oblivion (w/manual), Beyond Good and Evil, Space Rangers 2 and Indigo Prophecy Director's Cut.
I personally think the service is excellent, Eldar. It utilizes a download manager program which keeps track of all your downloads. Further, in the event you experience a power/modem glitch causing the d/l to be interrupted, it saves to the last non-corrupted data packet, so you can always resume where you left off. The download speeds are lightning quick, though you will experience a queue time the very first time you use it. Also, for the very first title, your download rate will start slow before accelerating to an astronomical rate. For when you purchase off D2D your bandwidth is equivalent to the most expensive top-of-the-line stream you would normally pay at fileplanet. Then again, I do have a 10 Mbps connection.
Note: Be sure to disable your firewall (if you can't be bothered to adjust the firewall/router ports) in order to launch the d/l manager from the web browser.
