The main romantic interest is a lesbian, the rest are either old women or prostitutes with plastic bodies!
I'm assuming you're talking about Judy. I don't think it's fair to call her the "main" romantic interest. It's just the one the marketing team decided to focus on. Almost certainly because she looks punk (tattoos, hair, nails, etc.); maybe also because she's lesbian and to virtual signal to game "journalists" (particularly after TW2 and TW3). Honestly, Judy isn't really that attractive to me because of the "punk". Tattoos especially are a turn off for me, especially when that heavy. Also, I'm pretty sure that the woman showed in the lifepaths trailer with the Nomad will be a romance option.
