i am looking to make this portion of the game rather powerful (in other words, i would like to allow the input to be simple: "Have Candle" and as complex: "Do you have any candles for sale?").
should i be looking at NLP or something else?
i am afraid that NLP routines in the game will be too resource heavy, however i would rather the immersiveness of conversations with NPCs to be deep, so i would be willing to sacrifice fancy graphics for this functionality.
has anyone else worked with this "conversational functionality" before?
