Somehow, it turns out that The First Descendant, the game PC Gamer's Morgan Park called "dollar store Destiny starring exclusively hot people," does not have jiggle physics.
I know this because, as noticed by GamesRadar, a developer has announced on Discord the «important news» that The First Descendant is getting jiggle physics. «I wanted to share some important news, so I decided to come online late tonight,» TFD_PD_Lee said in a translated message. «After a lengthy discussion with the AD today, a decision has been made to add the much-requested 'Jiggle Physics.' This was decided only a short while ago, so the details of when and how it will be implemented in the game are yet to be finalized and will be shared in future updates.» For those not in the know, jiggle physics is a catch-all term for systems that adds unmissably exaggerated oscillations to certain specific body parts.
Wikipedia, which has a whole section dedicated to it, says jiggle physics (which it describes more prosaically as "breast physics") dates back to 1992, in the fighting game Fatal Fury 2.
It's grown into near-ubiquity in the decades since, although it's not everyone's cup of tea. In 2018, for instance, Epic added and then quickly removed jiggle physics to Fortnite, calling it "embarrassing and unintended." How does a game studio unintentionally add jiggle physics to its characters?
This I do not know. Larian, on the other hand, seemingly opted to expand that particular field of technology by adding "schlong physics" to Baldur's Gate 3 in 2023.
