Tabletop Simulator: D&D DragonQuest and Dragon Strike
I have to share this here.
I've been dabbling a bit (as we all do, with little commitment and just a touch of "gee wow", before forgetting entirely what the fuss was about...) with Tabletop Simulator which I bought through Steam (in a sale, so I'm probably a year or so behind on content).
The Workshop area is filled with gems. I have no idea how most of this stuff gets by copyright rules, but when it comes to out-of-print games the TS Workshop offers a wonderfully opportunity to see how they can be played. Also it provides an opportunity for us recluses to play online with folk we'd never dream of actually meeting. ;)
