I've posted multiple times about my quest for a virtual tabletop solution. At the time I had been using ScreenMonkey, and was happy with it.
Then I picked up the September issue of Knights of the Dinner Table magazine. In the editorial Jolly Blackburn mentioned another solution in passing--Roll20.net. As I said, I've been happy with ScreenMonkey, but I like to check out "new shinies", so I did.
You may recall a few posts back that I said I was thinking about writing a plug-in for Google Hangouts to facilitate die rolling. Now it looks like I don't have to, as Roll20.net supports voice and video chat natively.
So the game moved over to Roll20 for a few trial sessions, and I have to say we won't be going back. The move to voice (we don't use webcams) has sped up the game to near-tabletop speeds, and has added 100% to the enjoyability of the game.
