Outdated World Designer Notes #9: Occasions

The next is an excerpt from the Designer Notes for Outdated World. The sport, a historic 4X set in classical antiquity, launched on July 1, 2021, and is out there for buy right here.

After ending Civ 3, I spent a protracted time frame engaged with the group to be taught what they did and didn’t like in regards to the sport, with a watch in direction of the patches and a possible sequel down the highway. Within the modding group, a standard criticism was that our editor lacked one thing referred to as “occasions” from Civ 2, which I realized meant a system for connecting triggers and results that might give video games a story arc. I didn’t instantly grasp the potential of such a system till I attempted out the group eventualities. I bear in mind two that stood out to me as a result of my actions pushed the story ahead – one recreated the journey to Moria in Fellowship of the Ring and the opposite was a retelling of Odysseus’s Mediterranean wanderings in The Odyssey. Neither was notably replayable, however they each have been attention-grabbing as a result of they’d purposeful tales constructed from solely a layer of occasions sitting on high of the bottom sport.

For awhile, I wasn’t positive what to do with this discovery as a result of I didn’t have a transparent imaginative and prescient for the way occasions may make a Civ sport higher, however I did be sure that our Python layer for Civ 4 had each triggers (calls from C++ to stub Python features) and results (the stub features may change the sport state). This technique led to many attention-grabbing Civ 4 mods and eventualities in addition to permitting the staff to jot down a sequence of occasions for Past the Sword, lots of which centered on pure disasters. Whereas these occasions have been a primary for the sequence, it additionally represented a little bit of an evolutionary useless finish as they weren’t carried ahead into Civ 5.

Nonetheless, I believed that occasions may play an attention-grabbing position in 4X gaming, and certainly observed that many different technique video games, together with the Galactic Civilization sequence, the Crusader Kings sequence, and Stellaris, have been utilizing them increasingly ceaselessly. Nonetheless, my greatest inspiration got here from probably the most text-heavy style of all of them – interactive fiction. The style was experiencing a renaissance within the UK, led by Inkle (80 Days, the Sorcery sequence) and Failbetter (Fallen London, Sunless Sea), and I started to quietly hang-out the GDC Narrative Summit whereas additionally interviewing the author/designers for my podcast to see what I may be taught. I additionally lastly discovered a bodily copy of King of Dragon Go, a cult hit from the 90s that was nonetheless unavailable on-line, maybe akin to discovering a disc of The Velvet Underground’s Loaded earlier than mp3s. The sport was a wild mixture of conventional 4X technique, clan administration simulation, and dynamic narrative constructed round random occasions that triggered primarily based on hidden components and which had unknown results (however which the participant would slowly be taught to anticipate).

I started to understand how essential narrative might be in a online game, the way it may pull gamers right into a sport world way more successfully than by merely making numbers go up, a trick that was maybe beginning to get previous in 4X gaming. To be clear, I had little interest in writing a narrative with imaginary characters and a starting, center, and finish (Who did I believe I used to be? A author?!?), and I used to be additionally pretty uncomfortable with opaque triggers and results which stored gamers at the hours of darkness, forcing them to play by really feel. Transparency is a crucial a part of my design aesthetic, and whereas it might be violated for impact sometimes, I didn’t wish to construct a whole system round it.

Maybe unsurprisingly, inspiration got here to me through board video games, particularly Tales of the Arabian Nights, an excellent journey sport constructed across the historical folktales of the Center East. The sport comes with a large storybook of over 2,000 occasions (some by Paul Murphy, author on Civ 3, the truth is) that are randomly drawn from a deck of playing cards after which cross-referenced with the character’s location, the participant’s choice, and the roll of a cube. Though one other participant would learn the occasion to create suspense and conceal the end result of the alternatives, the precise mechanics of how the sport selected every occasion was clear by necessity because the gamers did the work of discovering every occasion themselves. The readers would see how the occasions have been constructed and what would have occurred if the energetic character possessed a sure trait, in order that they in flip would anticipate the vary of potentialities on their very own flip.

The sport had an attention-grabbing system for linking occasions through free connections primarily based on abilities, traits, or treasures the character picked up over the course of the sport. A personality may change into Ensorcelled early within the sport, have the results of a later occasion change primarily based on being Ensorcelled, and eventually have the chance to take away the trait with an extra occasion. None of those occasions have been essentially going to occur throughout a single playthrough and, typically, potential narrative arcs have been left dangling with out decision. Nonetheless, when a cohesive sequence of randomly chosen occasions do come collectively to inform an actual story, it’s a magical feeling. What appealed to me about this method was that it was sturdy; there was no intricate occasion tree that might fail if one node was modified or stopped working. Moreover, loosely coupled occasions might be written by a big group of authors who may work in parallel with out shut coordination. One author may add an occasion which leads to your chief changing into a Drunk, and a unique author may add an occasion that requires the chief to be a Drunk (or, if that’s the case, forces the participant to take a sure choice), and these two writers have now created slightly story with out having mentioned something. Certainly, they might have been working years aside and maybe not even know one another. I’m very excited for the potential of group occasion packs which might co-exist with our 3,000+ occasions (and with one another) to create new narrative potentialities.

Thus, I had the essential blueprint for an occasion system – it might be a digital deck of occasion playing cards which every had a possible set off (similar to assembly a brand new nation), a set of necessities (a childless chief), and doable results (a overseas partner). When a set off happens, the sport finds all occasions within the deck legitimate for the present sport state after which chooses one randomly primarily based on the burden, likelihood, and precedence values of every occasion. The spine of the occasion system are the themes, that are a set of sport objects randomly chosen for every potential occasion. Topics may be something from a personality to a metropolis to a household and even to a legislation or know-how. Every topic can have a number of assessments to seek out the right one – an grownup baby of the chief who’s NOT the inheritor however IS a bloodthirsty schemer is an efficient instance of a really particular topic that may imply unhealthy issues for the present inheritor. Additional, the system can check for relationships between topics, similar to two nations which can be at battle with one another, the faith of your partner, or a personality who’s vengeful towards one other. The occasion choices can have an effect on any of the themes and may also be unlocked primarily based on the present scores or traits of the chief.

There are lots of different wrinkles to the system – for instance, it’s doable to hyperlink topics collectively for multi-step occasions similar to a duel – however this primary structure enabled the writing staff, led by Leyla Johnson, to create all kinds of occasions that basically change the circulation of the sport. Dynamic random occasions disrupt the regular circulation of a 4X sport, which might typically devolve into deciding which bucket ought to replenish and at what pace. Maybe an occasion supplies a sudden burst of Orders that permits the participant to maneuver sufficient models to defend a metropolis that was nearly to fall. Or, maybe sending certainly one of your youngsters out to discover the world results in the founding of a brand new world faith. Or, maybe a extreme fight harm signifies that Alexander might want to abandon the sphere and change into the Realized as an alternative. A standard theme of Outdated World’s design is avoiding predictable and boring video games the place the identical actions result in the identical outcomes, and the occasion system is a crucial instrument to make sure no two video games are ever the identical.
