All of the main companions are young, fit and interested in you. Yes, even the racist alien. And the guy whose romantic entanglement with a literal goddess is part of his story. No loyal widow/SO back home/married to their duty/asexual/just not that into you, etc allowed. That already felt dodgy before you find out everyone makes the first move and have to be turned down. Everyone.
Platonic relationships got shafted hard and obviously. I should not feel like actually getting to know one of my companions is the reward for pursuing them. That's backwards AF.
The romances exist in a bubble. WAY more effort was put into the reactivity of taking LIs to see some twins than to their LI literally dying in front of them. Hello?
There are SEVERAL occasions where the developers compromised their own characters in favor of sex/romance. A prime example being Shadowheart. Her initial stance is one of reservation. She will tell the player that Shar discouraged relationships so flings were indulged in secret. Cue Act 3, where you can discover any number of fascinating things, like how apparently Shar has multiple personalities and actually does encourage flings so the brothel thing is fine. Or double fine if you brought Halsin since SH has been thirsting over him for a while. Or how Shadowheart is an amnesiac commenting on how relationship drama is so last century fr fr ong.
Halsin's everything is the second example.
Ever noticed how much less a romance with non-Ascended Astarion gets? A friend of mine certainly did. How weird!
Marketing.
I still have no idea what purpose customizing genitalia serves.
Same goes for the sex scenes. They are not done particularly well animation wise, nor tastefully content wise and Larian appears to have buyer's remorse with some of what they launched with. So what was the point?
