@JeremyECrawford Do you ever refer to the original TSR books when working, or is the 5th edition now completely independent of the game's origins? How do you think of the historical line of development throughout the many versions?

As part of creating the current edition of D&D, our team delved into all of the game's previous editions. As part of our ongoing work, we continue to refer to other editions for research and inspiration. #DnD https://t.co/oxOZamVXRt

I hope you refer to 4th edition frequently, rather than seccumbing to the haters! We refer to all of the previous editions, including 4th. I did too much work on 4th to ignore it.
