The Helena quest and the sidequest with the dommy centaur whose name I have forgotten were new, as were the entire rat warrens plus Axel content, as well as the Enforcer inspector questline, and the teleport questline. There are also now Enforcer patrols you can encounter in backalley tiles, you can get the offspring map from the city center, and there was some father's day content added. So let's not pretend as if nothing new was added at all.
And not all of it might have been my cup of tea (I could have done without the whole Helena thing, especially that centaur is just obnoxious), but I genuinely like the Rate Warrens, the Enforcer Inspector and the teleport questlines. Even if the Rat Warrens took like 8 months or so to get fully implemented, which is imho pretty slow.
