From Steam: GM Forge is a Standalone Virtual Tabletop with competitive features, making it a good affordable alternative. When you buy a copy of GM Forge, your friends join you through their web browser without purchasing a copy. It has all the competitive features in other virtual tabletops, as well as some impressive new innovative ideas built with the average GM in mind.
GM Forge is a sandbox for GMs, and has 6 sample systems available on the workshop with some automation setup for basic play, with the option of downloading additional user created content and mods through the steam workshop!
