The upcoming Fable title is poised to recapture the spirit of the original Lionhead games, but its complex reactive world appears to be deeply indebted to the groundbreaking artificial intelligence systems pioneered by The Elder Scrolls IV: Oblivion. This approach to NPC behavior, where in-game characters exhibit routines and react dynamically to player actions, was a hallmark of Oblivion and is now being brought forward into Fable's new iteration.
In a recent gameplay demonstration, Fable showcased how the disposition of NPCs changes perceptibly based on player choices. For instance, after a hero saves a talking pig, the townsfolk of Silverbrook display altered expressions, reflecting that a hidden numerical value has been adjusted. These changes are tied to character traits; Jack the Beggar might approve of a virtuous act, while Megan the Merchant values a shrewd business decision. Associate Game Director Craig Littler described this as a "complex, nuanced take on reality," aiming to mirror the multi-faceted nature of real life where perspectives are subjective.
However, the appeal of Fable's reputation systems, as noted by IGN writer Jeremy Peel, lies not in their realism but in their demonstrable mechanics. Player decisions are translated into tags such as Kind, Rich, Killer, Charming, Criminal, or Entrepreneur. These tags are then cross-referenced with individual NPCs' preferences, influencing everything from shop prices to romantic availability and how strangers greet the player. While these reactions are intended to surprise players and create a sense of being watched and judged by the inhabitants of Albion, they are also designed to be manipulated. Players can game the system for favorable outcomes or bypass consequences by influencing public opinion through other means.
This observable system brings to mind the legacy of Oblivion's Radiant AI. Bethesda's 2006 title aimed to imbue its NPCs with life through assigned routines, dictating their daily commutes to work, leisure, and even religious services. Oblivion's NPCs would dynamically seek out places to eat lunch and engage in spontaneous conversations, offering opportunities for players to influence them on a personal level. Interacting with Oblivion's "persuasion" wheel, employing options like Joke, Admire, Boast, and Coerce, could quickly foster kinship, potentially leading NPCs to overlook minor transgressions.
Despite the ambition, the seams of Oblivion's Radiant AI were often visible, with routines occasionally breaking down. A notable example involved a soldier in the Daedric planes inquiring about a comrade's well-being while lava pooled around his feet. In subsequent Bethesda titles like Skyrim, Radiant AI became more subtle. While interactions still occurred, such as NPCs arguing over a dropped item and a guard intervening, much of the data tracking operated invisibly until it triggered a quest or event. This subtler approach benefited the atmospheric density of games like Fallout 4 and Starfield, avoiding fourth-wall-breaking eccentricities.
Following Oblivion, few high-profile developers openly marketed games with similar Radiant-like AI. Watch Dogs: Legion, released in 2020, was a notable exception. Directed by Clint Hocking, who had previously worked on Far Cry 2's reactive NPC systems, Legion allowed players to recruit nearly any citizen in London. Non-recruited NPCs maintained daily schedules and relationships that influenced their perception of the player. An accidental good deed, like running down an individual who had wronged another citizen, could make the victim more receptive to joining the player's hacker collective.
Despite its potential, the systemic events in Watch Dogs: Legion often occurred on the periphery of its main narrative, and the game ultimately proved disappointing. The series' future stalled, dimming hopes for a revival of its advanced NPC systems. However, the unexpected release of The Elder Scrolls IV: Oblivion Remastered years later saw a resurgence of interest in its clockwork NPCs, rehabilitating the game's reputation and highlighting the charm of its complex routines in an era where such systems had become less prominent.
This renewed public enthusiasm for malleable and reactive NPCs has created an opportunity for Playground Games with Fable. Ideas previously explored in earlier Fable titles, like the "touch" mechanic allowing players to guide NPCs, have been expanded upon. For example, a beggar on the street can now be recruited to work at a player-invested pub, and a nosy neighbor who observes multiple NPC marriages within a settlement might resort to blackmail. The developers aim to avoid the narrative-system disconnect that impacted Watch Dogs: Legion. The death of a character like Dave the Giant could significantly alter the economy and social fabric of Silverbrook, potentially increasing tourism and driving up housing prices, making it difficult to house the local homeless population. With several years of development, Fable has the potential to deliver on its ambitious promise, appearing quite "Radiant" even in the shadow of its influences.
