I'm curious if this whole PC game rental thing will catch on. I'm surprised more places - i.e. Steam, since they always seem to be way ahead of the rest of the world for digital gaming ideas - didn't come up w/ something like this.
Then again, "Free Weekends" for certain games when Steam actually has them IS a way better idea, anyways.
The really bad thing I can see about what D2D is doing - say "bye-bye" to game demos. Though, most game demos are really short - too short for their own good. Sometimes, they're not even a good indication of how the game will be. The good thing is here, you got access to the whole game - so you can test how it runs, if it's any good, etc etc. Bad part - it's only for a mere 5 hours.
Also, seems like we're getting less and less of PC game demos unfortunately, anyways.
