We've finally gotten to play Red Dead Redemption 2, and there's quite a lot to take in. We had largely been in the dark on what to expect from many areas of the game, although an earlier gameplay trailer did reveal new mechanics behind how protagonist Arthur Morgan will interact with the world, his gang, and even his horses and assorted wildlife. Rockstar is making sure that the world and its inhabitants can be interacted with in ways aside from shoot-outs, and one large part of that is an expanded conversation system.

In the trailer, Morgan is seen interacting with characters in a variety of ways based on contextual conversation prompts. Two prompts are available at a time, and they change based on actions you've already taken. We see prompts for Greet, Defuse, Antagonize, Threaten, Dismiss, Beat, Rob, and Choke, among others.
