This video is the "Dark and Terrible" campaign Gamemastered by Abraham from Talking About Games Channel.
It's a primary example of how the Gamemaster and Players interact when they are actually roleplaying.

And no... you will never see this happen with Seth Skorkowsky, Matt Coleville, DM's Lair or Bob the Worldbuilder... because THEY DO NOT KNOW HOW TO ROLEPLAY.
The basics are:
- PLAYER: Stay in Character when talking during the Game
- PLAYER: Always say where you are moving or what you are doing (Limit to one action's worth)
- PLAYER: Your Character is not "you" it is a Construct of the collective imagination of the group.
- PLAYER: Do not ask out-of-character questions (yes Abe tells you how this is done below, last link)
- GM/DM: Stay in Narration form
- GM/DM: Do NOT move the players, that's the player's action, not yours.
These are more links to video's Abe has put together to help!

Abraham is a true master of Roleplay, something that I hope to be able to replicate myself one day.
Abraham has been a great mentor and exemplar of the ROLEPLAY experience.
Even just applying the basics of what he talks about in his videos will help you greatly in your experience, however it takes the willingness of the GM and Players to make this all work.
