Hi, I can't ignore all the positive things I'm hearing about D100 and I'm ready to give it a try. I suspect I'm going to really enjoy it and would like to ask what is recommended beyond the book 1. I'd prefer to place a single order with DriveThru. I'd guess Book 1 & 2 for my initial order but thought it worth asking the expert. ;) Also, Is there a Discord Server dedicated to D100? Thank you!!!
