It sounds like a good deal, except, in D&DO's case, only available for new accounts. This means that any progress a player makes in the free portion of these free-to-play games will be scrapped if they want to save some money by purchasing Direct2Drive's bundle.
Furthermore, Direct2Drive advertises these games by claiming you can "unleash your free-to-play games", but offers no free download. It also doesn't even link to the game's website where a free version could be obtained. The service requires a purchase before any of these games, which are inherently "free-to-play", can be played.
Sounds like a good idea, but obviously needs some work.
