This is not unusual, and they need it for protection from others claiming they stole an idea. It's why authors and TV writers tell you to never send them ideas or tag them with ideas.
Same. Every once in awhile I try, for comedic effect. I think I've had one player, maybe two, in nearly fifty years who did. I think it's less common than most think, but I have no idea if that's true.
Agreed. I have so many thoughts about those last years of episodes.... But no interest in rehashing that conversation. I'll never read another of his books, if he writes more anyway.
I still think 2.5d is the way to go. Minis on a table, with a few props like doors and chests and a tree here and there.... Like playing at home with minis.
Not tying Sigil to dndbeyond in the first place was a weird decision. They have a very good character builder! Use it.
I disagree. A great 3d system would be a game changer. It's just so hard. Making it 3d doesn't make it a video game at all. I didn't get this argument at all. Doing all the math makes it more of one.... Though I agree most want that.
