I don't really understand the asset pack sales like https://assetstore.unity.com/g/best-of-2018 This pack mixes low poly & realistic PBR and then 2d animation (anime?) & 3D skinning/animation! What is the chance of anyone needing such a variety of styles? Then you have mobile video recording. It's great to celebrate the best assets but would it not be better to put them individually on sale?
