I loved how you get attached to the character. At first i did not feel anything for V, I did not even feel sorry for Jackie, but once you get to chapter 2 and start doing side quests with Panam, Judy, Kerry and River, you develop the connection with V and all the main characters. Spoiler ahead! I did the ending with Rogue and Jonnie, when he gets to make a final choice, I've mad him stay with Alt, and the way V was hysterical about it was very strong. Romance was a big part of my connection with V. She became human, girl who needs some love and escape in her crazy situation. She had romance with River, and when she gets to make the last call and talks to him, this was heartbreaking. All I wanted was for her to get back to him, no matter what, even for a short time, and thats why i left Jonnie with Alt. Seeing V and River together again after the return was bittersweet and I literally cried when she was on the space station.
I honestly think those romance lines need much more work, River line after the sex scene almost vanishes. Thats not how relationship work: they need to be able to communicate, do more together, talk like lovebirds talk, make love, solve more quests, go on for a date... thats just unfair. They needed to discuss V's condition, they needed to say goodbye... I hope for the DLC to see more of River, but as I read reviews, a lot of players what to see more of other romance/friendship connections to develop and it makes sense. I totally understand the need and think that for players those human connections, those character stories are something that makes the game great and makes you cry in the end.
