First: Since you only need the host with a subscription to play online will there be a way to assign someone ‘DM privileges’ in case the DM isn’t the host?
I’m a part of several different communities where DM’s are routinely outsourced and brought in by players. Having the ability for a community leader to host a game and pass along the ability to control the important functions to someone in the online game would be helpful. Tabletop Simulator has a similar function with their seating where one color is a ‘GM Color’ that can see everything and has access to game functions that normal players do not but a host is still in control and can assign or remove higher privileges.
Second: With all the content in the Marketplace would you consider a higher priced monthly subscription that included use of marketplace assets as long the subscription is held? With a tip jar being planned having something like this would be great, especially for groups or DMs that run multiple games weekly.
