It's basically everyone assigns a role to themselves and improvise what to say. The other person continues to respond.
There is no narration, the dialogue is supposed to give information on the setting and characters as well.

Some should start, not me though.

    I mean are we continuing the previous one with more people or should we start a new one?

      Texas you can play too. I think we should just start all over since so many people are here, what do you guys think?
      Lets do an adventure one this time?

        Sure let's begin our adventure, where do we start in a tavern?

          System Online.

          Greetings players and welcome to Last Comment, a co-op game about saving the world.
          An unknown user accidentally started a war between various large factions.
          The war went on for several days and many lives were lost.
          Forum Bot Queen, the only entity with the power to stop the war, gave the warriors a chance to prove themselves but in reality it was a test.
          Eventually a warrior was enlightened and shared their newfound knowledge with others
          Peace was declared.
          But the only person who could enforce this peace, the Forum Bot Queen, was nowhere to be found.

          Players, you have been summoned to solve this situation.
          Do you wish to begin this journey?

            “Confirm.” I answered from within the system space. A soft light gradually enveloped me as my surroundings started to change. Materializing in front of me was the warm inside of what looked to be a tavern. I looked around the dozens of tables and didn’t spot anyone.

            ‘I guess I must be the first one here’.

            I looked to the bar and standing there was a well-kept, broad-shouldered man with a handlebar mustache cleaning the inside of a mug. He met my glance with a nod and continued working.

            Without anything else to look at, I looked down at myself. I was wearing a dark cloak with leather gear under it and a pair of sharp, iron daggers at my waist. I also had a vial of poison hidden in an easy to access pocket. I was a rogue.

            Once I had a good grasp of my situation, I decided to ponder on the story the system introduced while waiting for other players to join.

              I looked at the prompt in front of me in a daze, I was confused. After a few seconds I finally realized I was no longer in my room and in some mysterious place full of different people.

              I looked at myself and saw I was wearing a cloack with leather gear that looked to be a beginner's equipment in an rpg. My weapon was two short swords at my waist, I look like a swordsman.

              While I was checking myself out, I noticed that there was someone that looked to have a simliar cloak and leather armor like mine. I approach him while looking warily at the other beings in the bar room. Even though I was afraid, I was at the same time excited as to what was going to happen.

              "Hi stranger, do you know what's happening?"

                          "Confirm" are the last words i said before finding my self into a place that looked like a tavern. I looked around and saw some boys dressed exactly like me. I got closer.
                          " hey"
