I used StripSaver 2 and VG2 before this site came out.
StripSaver was a standalone program that Totem put out that was just a screensaver. It had most of the same girls as VG2, but there were some differences. When VGHD was first released (it may have been only during the Beta), there was no screensaver option. They essentially combined two products into one with VGHD (among many other improvements).
As for the Dovile/Divine crossover, it's just one of many girls that were initially released on VG2/SS2 and then released here also at some point. Many of the older cards were re-releases. I'd say if a card number is within the first 100, there's a 90% chance or better that it's a re-released card.
