I am not a fan of mobile ports of games, mostly for the generally better features that are offered and are never brought to the main/original game.

Dead by Daylight's mobile port has fancy cosmetics and game modes (only recently was the main game lucky enough to get like one (1) outfit ported over every several months).

While not a direct port, Animal Crossing Pocket Camp has pretty much all the old furniture sets from older games in addition to thousands of new furniture that animals can interact with. New Horizons was very anemic in comparison, even missing core features from previous games that were never added in. Pocket Camp got like 7 years of support and updates, New Horizons got barely a year of drip-fed content that should have been available at launch.

FFXIV's mobile port makes me a bit nervous. We're already in the midst of a middling expansion and the content drought feels more noticeable than ever before, I'd rather not see the attention be focused on the port.

Yes. I know mobile ports are made by entirely different teams, and the monetization is what enables them to add these new features anyway. But if the mobile game winds up getting some neat QoL changes or features that have been wanted in the main game for a long time, I might have an aneurysm.
