Not that my opinion matters, or anyone's opinion here will effect the way the dev continues the story, but the Ariel/Haylee thing is stupid. I'm PRAYING this doesn't end up being a "major choice" because that would be dumb. The dev is going for a quasi-realistic story, and in reality choosing between the two would be a disaster. The realistic choice for a guy in that position, with 14 other women at his disposal to potentially fuck; is to cut both girls loose. It simply wouldn't be worth the hassle (especially the way the two of them constantly bicker about EVERYTHING). In reality, I'd stay as far away from both of them as I possibly could.
Also, Ariel has Stage 5 Clinger written all over her.
