據最新爆料，《俠盜獵車手6》（GTA6）在NPC真實感上再下血本。除了主角之外，光是路人NPC的錄製台詞據傳就多達數十萬句，並且搭配不同的觸發情境，只為將遊戲的沉浸感與互動感打造得更細膩。
據推特賬號「GTA 6 Countdown」從Rockstar Games內部負責音頻回歸測試與字幕驗證的工作人員處獲悉，此次R星延續了《碧血狂殺2》中追求超真實世界的精神，為環境NPC準備了數十萬句台詞並配上了字幕。這些台詞並非隨機播放，而是針對不同觸發情境構建了完整的對話邏輯系統，形成一個超大型資料庫。
New alleged GTA 6 leak with details about the game’s advanced NPC dialogue system: - This information comes from someone who allegedly worked on audio regression and subtitles validation - There are hundreds of thousands of recorded lines just for ambient/world NPCs, not story or main characters, just people walking around, reacting, talking, calling out - They replayed random world interactions, making sure lines triggered correctly, matched subtitles and didn’t overlap - The NPC dialogue system isn’t like GTAV’s simple random pool of lines. It’s fully structured with detailed tags and categories - Every line is labeled in a very specific way depending on context, situation, and variation, making it more like a database than a loose collection of voice lines - They had access to a debug browser where they could see the line IDs and tags The system relies heavily on conditional dialogue. NPCs don’t just say random lines, they react based on specific conditions such as: - Whether they saw you commit a crime or only heard about it - Whether they recognize you or not -Whether it’s their first reaction or a repeated encounter - Time of day (day vs night tone differences) - Weather conditions (NPCs sound more annoyed in heat/rain variants) - There were bugs where the wrong emotional intensity would play because the system pulled from the wrong tag group, like a calm line triggering during a panic state. - Other bugs involved chain steps triggering out of order and people were arguing backwards Actors are recording multiple versions of the same line with different: - Emotions - Intensity levels - Phrasings for the same situation - Different demographic variations so NPCs don’t all sound the same - There are entire sets of lines that are nearly identical but differ slightly in tone, such as neutral, panicked, whispering, or injured versions of the same situation - The game actually uses these variations depending on what’s happening in real time - There’s a dialogue decay system that avoids repeating the same lines by pulling from deeper variants if you stay in an area for too long - There are conversation chains so NPCs don’t just say one-off lines - There are mini conversations between NPCs where person A reacts then person B responds then person A escalates or backs off - The system also includes social awareness dialogue where NPCs can comment on things happening in the world, such as increased crime, police presence, or referencing viral clips - There are lines referencing the player’s reputation or recent actions locally, making the environment feel more responsive to what the player has been doing - NPCs feeling 「alive」 isn’t just about AI behavior. It’s heavily driven by the enormous amount of structured, context-aware dialogue and the systems designed to deliver it in a natural, non-repetitive way The scale and complexity of all this helps explain why voice actors (in relation to SAG-AFTRA concerns) might push back because it’s not a normal voice voice acting gig anymore, it’s like building a database. This information remains unconfirmed but it doesn’t seem that far fetched, considering that RDR2 had 450,000 lines of dialogue with a deep greet/antagonize system. (via u/Brave_Plan_9659)
例如，當玩家犯罪時，路人是否親眼目睹、是否認得玩家、是否第一次碰到等因素，都會影響台詞與語氣。天氣炎熱時，NPC也會表現得更煩躁。目前許多配音演員還在錄製同一句台詞的不同版本，甚至考慮到NPC的種族與社群差異，用詞也會截然不同。
此外，遊戲系統會從海量台詞庫中持續挑選合適的台詞，避免玩家在同一地點久留時聽到重複對話。路人NPC之間也會互相聊天互動，並對彼此做出真實的情感反應。若爆料屬實，R星將再次擦亮「細節狂魔」的招牌，為玩家帶來更加逼真的遊戲世界。
