This mod adds a system of dialogue interaction between the player and the NPC. You will be able to talk to EVERY individual passer-by in the game, choosing the options you like. Depending on the situation, you will be able to "greet" or "show hostility" in dialogues with the interlocutor.
Installation: Move DialogueSystem.dll to your "scripts" folder. The latest versions of ScriptHookV and ScriptHookVDotNet are also required.
