Greetings! I just started enrolled in school for video game design and I had an idea for dialogue in a game I plan to develop, but I wasn't sure where to go or who to ask. I am designing a RPG game that requires NPC character interaction, but I want to avoid that dialogue style where the NPC speaks, and then the player is given a list of responses to choose from. Instead, I would like to go back to the more interactive style common in classic games where the player's character encounters a NPC and two dialogue boxes appear; one the player's, the other's NPC. In the NPC dialogue box will say something like "greetings traveler" or another greeting (friendly or otherwise). Now the player gets to type in his or her dialogue box a response--any response he or she feels like. I understand it's a lot of work as there are so many responses, words, topics, a player can type, but this freedom of speech and interaction is critical for the goal of this character-based video game. I am not making a text adventure game, but a visual RPG that uses text-based adventure elements in a conversation style with NPCs. Something like that 1960's AI program Eliza but instead of psychology topics, the conversation would motivate plot, character, and conflict. Thank you in advance for any advice or program suggestions that would allow this.
