I’ll use a unique instance to reply your query immediately. There’s a widely known long-running MMORPG referred to as Star Wars: The Previous Republic that was well-known for its companion characters as a significant recreation function.
ALTThe way in which that the companion system was constructed for launch was designed round each class having an equal variety of companions throughout the knowledge. Companions at launch had been mapped by class – each participant class had six totally different companions, every with a set function (melee tank, ranged tank, melee DPS, ranged DPS, healer, ship droid) in a particular numbered slot. In the entire code programs that had something to do with companions, the code wouldn’t ask for a particular companion by ID quantity, however relatively by the participant’s class and companion slot quantity. The system was constructed such that companion lookup couldn’t be sparse (that’s, you couldn’t have empty companion slots for any class), or programs like companion affection, gear, companion stats and stat scaling, many components of fight, companion UI, sure cinematics, and so forth. would fail in a cascade. Each class needed to have the identical variety of companions or every kind of recreation programs would break. This additionally meant that there wasn’t simply two totally different faction ship droids, there have been eight (a unique one for every class).
ALTIt was when the sport designers added the primary and second further companions to the unique roster that they bumped into the wall. They couldn’t add simply one companion – they’d so as to add eight companions – a unique model of the brand new companion for every class. The prices had been so nice that the management deemed it too costly to construct new companions after the primary two (HK-51 and Treek). It additionally meant that there was no means that they might reuse current companions for different lessons – the Sith Warrior couldn’t ever recruit a companion character that was designed for the Imperial Agent, as a result of it wouldn’t be the identical companion, it’d should be a separate occasion of that outdated companion knowledge. New companion characters had been some of the extremely requested and standard options amongst gamers, however really including them to the sport was a nightmare by way of the quantity of labor that wanted to be achieved and complexity of information (since design quailed on the considered having to maintain monitor of as much as eight totally different variations of each new companion added to the sport). This drawback was a steady thorn within the facet of the management too as a result of they knew this might open up large new alternatives – faction reward companions, microtransaction companions, momentary companions that would really die as a part of the story, totally different variations of companions, and so forth. – however couldn’t feasibly do something about it as a result of improvement value of getting to rebuild the whole system.
ALTUltimately, circumstances granted the SWTOR group further headcount for a yr and the management correctly tasked a strike group of engineers and designers for almost the whole growth cycle to rebuild the companion system from the bottom up with a purpose to decouple the participant lessons from their static companion slots. For the primary time, designers may set an inventory of participant lessons that the companion could possibly be recruited by without having to create a reproduction of that companion’s knowledge for every class. All lessons may share the identical companion’s knowledge, which meant that lessons may recruit every others’ companions, and that new companions had been a lot, a lot simpler so as to add to the sport. Design would now not must create eight totally different variations of the identical companion anymore.
ALTAs you will have surmised, the explanation that it was so costly so as to add unanticipated performance in later is as a result of lots of different important programs had been constructed upon the assumptions made throughout that preliminary implementation. Altering the underlying system meant that the entire different programs constructed on high of it will both fail spectacularly, or would additionally have to be rebuilt to work with the brand new hotness. These recreation programs don’t exist in a vacuum – there are sometimes shockwaves that have an effect on different secondary programs which may set off their very own shockwaves to have an effect on tertiary programs, and so forth. It isn’t at all times as enormous a problem as SWTOR’s companion system, however it’s a actually good instance of dangerous assumptions made throughout preliminary improvement haunting the group for years after launch.
