Are you still going to be podcasting audio only? A VTT eliminates the need for much of the 'theater of the mind' exposition and description, which might actually be a hindrance to your podcast. That said, I use FG and here are the things I usually suggest to others considering it:
- if you get the $10/month ultimate license (recommended!), it's the only cost you'll incur, other than any adventure modules you might buy. Your players just need the free demo and they will be able to connect to your game.
- I highly recommend buying a cheap one-shot adventure module (AAW ones are pretty good) from the FG store or DMsGuild for learning. There's little enough content that it won't get confusing in the beginning. The official WOTC adventure modules are great, but there is a LOT of content in them, and it can be overwhelming in the FG UI.
- watch videos about sharing modules, making characters, maps and tokens, the combat tracker, and effects (in that order). Those are the most important things a DM needs to know in order to use FG. (There's loads more features of course, but that covers what you'll be doing 90% of the time).
- my best protip is to use the quick slots at the bottom of the screen for almost everything. You can drag just about ANYTHING in them, and there are I think 96 of them or something ridiculous like that. You can minimize windows, but I find it's quicker to just drag it into a quick slot and close it.
- if you are making your own campaign, you'll want to give yourself more time to get to know the app before you jump in and start DMing. I love it, but it's very quirky, and I learn new things about it every time I play.
- VTTs are a great tool, but they aren't 100% necessary. So only use what's useful to you and actually makes your games more enjoyable. For anything else, do it old school.
Good luck!
Thanks!
And, no this will be just for fun. The problem you describe is exactly why we normally play TOTM. I'm wanting to use this asa chance to do something different.
