Roll20: Web-based online virtual tabletop for all roleplaying games (RPGs)
Who's this for? Roll20 is a virtual tabletop. So it's all about taking any game that you traditionally play on a table (especially pen and paper RPGs and board games), and bringing it online. Play with friends who've moved across the country, or find a completely new gaming group online. Roll20 is easy to use, so dive in and get started! Is this really free?
