@LordEntrails: Yes, something like that.
What does having an Ultimate license get you that you feel is worth the extra $6 a month?
When you buy a D&D 5e product as a FG product, what is that getting you that say a book or a pdf doesn't get you?
Could you like describe the experience of using your favorite FG product?
I'm not
@LordEntrails, but, my experience is very similar to his - been using Fantasy Grounds for 5 years or so with an Ultimate License. I've been buying books sporadically over the years and I'm currently using Ghosts of Saltmarsh.
Oh, one thing to be aware of - if your router does not port forward, it can be a trick to run Fantasy Grounds. You have to use Hamachi - it's not terribly difficult, but, it can be a PITA. Google the Fantasy Grounds forums and they have an excellent how to guide for setting that up. OTOH, if your router supports port forwarding, then don't worry about it. FG is rock solid in terms of connectivity. We might drop a user once every couple of sessions, and, frankly, that's probably on their end rather than a server issue. Some of us are using pretty old PC's.
Frankly, someone in the group is going to need that Ultimate License since that's probably the best way to run the game. Otherwise, everyone has to buy a regular license. It just makes a lot more economic sense for the group to collectively buy an ultimate license and then just play. But, it does depend on your group. And how often you play. If you DM in two groups, for example, then an Ultimate License makes sense.
The biggest thing you get with buying FG material is automation. And, as much as I bitch about FG (and I do have some very large issues with FG - mostly on the UI side) the automation is FANTASTIC. You want to add a level to a character, drag and drop the level, everything is automatically calculated, right down to the DC's for spells. You want to make an adventure? Everything is drag and drop. And, that automation continues during play as well - your PC has a concentration spell up and gets hit? The game automatically rolls your concentration check for you and removes the spell if you fail. Stuff like that.
So, yeah, if you buy, say, Ghosts of Saltmarsh, you could literally boot up your computer, get everyone to join and start running without any prep.
