@Starryk, what I really object to is getting a type of card that I really don't like through subscription, without any choice in the matter.
When DB came out I thought we had seen the last of duo cards on VG, and I'm kind of disapponted that they are still appearing. It really makes me feel a bit cheated to spend money on a subscription and then get a product that I wouldn't buy given the choice, and will probably never even look at except perhaps to review for my web site.
What I love about VG is the illusion of a one on one experience with a girl on my screen. Having two girls together just spoils that for me, especially where they are concentrating on each other rather than the viewer. Admittedly, Ariel and Trisha's "Big Cuddle" card has a few clips where both girls maintain the illusion and have a lot of fun into the bargain. But those are the exception rather than the rule.
