tbudd said: I understand the point about converting a dungeon to roll20 (maps, handouts, etc.), but what is done to convert a rule book? What integration is there for a rule book into roll20? It might be worthwhile to purchase a rule book for roll20, if there was a character generator for that rule book, but AFAIK there is no such integration. The "integration" such as it is, allows me to look at the rules in roll20 or I could not buy the book and just open another browser tab. Seems like the choice is clear. Have you looked into this at all? I'm not sure I understand what you are saying. Rulebooks on Roll20 are Compendiums. Most feature drag and drop feature additions (equipment, abilities, spells, etc.) and some even use Charactermancer, the built-in character generator, which has integration with the given compendium. Sure, there are only a handful of systems that have compendiums (it's hugely labor-intensive to create), but those handful comprise 80-90 percent of the games played by the 6 million users on Roll20.
