A user has created a conversational “RPG” that adventures in the world of swords and magic using the large-scale language model “GPT-4” released by OpenAI as a game engine. With “GPT-4”, the AI behaves like a game master through conversation, and the point that an adventure that is too free develops is attracting attention.
On March 14, OpenAI released the next-generation large-scale language model “GPT-4”. Compared to the conventional “GPT-3”, the reasoning ability and simplicity of the solution have improved dramatically, and immediately after the release of OpenAI, external developers have published services using “GPT-4” one after the other.
Takayuki Fukatsu, a Japanese designer, created an RPG using the GPT-4. Mr. Fukatsu is the representative of the creative farm THE GUILD and the CXO (Chief Experience Officer) of the content posting platform note. He posted a note article with the following tweet on March 16th.“Chat Reincarnation ~ A Childhood Friend Who Should Have Died Became a Hero in Another World (Trial Version)](Hereafter, Chat Tensei) has been released.
The “Chat Tensei” stage is a world of swords and magic. It’s a story game where a childhood friend reincarnated as a hero gives advice so he can defeat the demon king. What differs from general games is that the player gives advice to the hero in the game through chat. At that time, “GPT-4” takes the role of game master and guides the player based on the settings. Players are required to give appropriate answers according to the situation, and while chatting in real time with their childhood friend who has become a hero, they will go on an adventure together and aim for the final goal of the game, by subdue the Demon King. In other words, “Tensei Chat” can be said to be a single-player TRPG scenario that can be played without a real game master.
In addition, since this game uses “GPT-4” with ChatGPT, a contract is required for the paid version of ChatGPT, “ChatGPT Plus”. If you are a “ChatGPT Plus” subscriber, you can start playing by entering the dozens of lines of tips described in Mr. Fukatsu’s note article.
It should be noted that the actual content of the prompt is written as if it were explaining the rules to a human being. When defining the position of AI as “You are the master of the game”, it clearly communicates a series of rules such as “Show elements such as story progress / growing crisis / technological innovation / liking level at the end of the conversation”. That’s why. The high performance that fulfills his role firmly as a human being is interesting and terrifying.
What the heroine is looking for is modern knowledge with prompt settings, but you can also aim to expand various rules in cooperation with AI, such as combining it with magic. How to play “Chat Tensei” is free. Another feature is that real-time chatting with characters enhances the sense of immersion in the game. Lots of play and clear reports have already arrived on Twitter, and it shows excitement. You can see how users aim to overthrow the devil in their own way, entrusting themselves to the processing power of “GPT-4”.
On March 15, Mr. Fukatsu released the school romance survival game “Tokimeki of the Dead ~ Koi no Apocalypse (Trial Version)” and the Cthulhu Mythos survival game “Dokitto☆Arkham University” rice field. Mr. Fukatsu has already produced several games using “GPT-4”. It can be said that it is also a feature that can be applied to other games by modifying the prompt.
In addition to this, foreign Twitter users also tried to play text-based Pokemon Emerald using “GPT-4”. Although it is text-based, you can see that the interaction based on the game system, such as choosing a Pokemon from the first three, type, level, and move, is going on. Game creation and game reproduction using “GPT-4” can speed up more and more in the future.
OpenAI has already released the “GPT-4 API” to some developers. The previous models “GPT-3” and “GPT-3.5” have also shown the possibility of being used in different areas of game development (related article). The development of various services using the newly released “GPT-4” is moving forward with furious momentum, and may have a great impact on the game industry in the future, including “GPT-4 API” for developers.
“Chat Tensei ~ A childhood friend who should have died became a hero in another world (trial version)” is available as a prompt in Mr. Fukatsu’s note. If you are a “ChatGPT Plus” subscriber, you can start playing by entering the dozens of lines of tips described in Mr. Fukatsu’s note article.
