I've been using Hero Lab for a long time now, and I think it's a great piece of software that helps me a lot in preparing my games (as GM) and also making characters (for when I'm a player). Now I heard of Realm Works by the same company, which came out last year sometimes, but I have never tried it. It definitely sounds interesting, but at the same time, also sounds like it has at least some features Roll20 already has. I'm not sure, maybe that's completely wrong, just going by what I find on the website. Like Player views, Fog of War etc. So I'm not sure, is this just another VTT tool, or is it something completely else and actually very useful even when the actual game is on Roll20?
