For example, if I have wishlisted AC Odyssey on PS4 Digital (currently 60 USD), we can presume I am interested in AC Antiquity Pack on PS4 Digital (currently 25 USD) which includes it, even if I haven’t wishlisted AC Antiquity Pack. In addition to bundles, the same logic applies to deluxe versions that include DLC.
Not only this, but also not having to add all the individual pieces or hiding all the parts of a collection to avoid having them pop up would be nice
