Obviously the developer has created a game people enjoy which is why there are so many discussions about Annie's character [ . . . ]
Rarely do you get an insight into Annie's thoughts and feelings which make her an unsympathetic charecter.
I will give you two examples.
1. If you catch Annie and Ryan and confront them you throw Ryan out of your house. Later he texts Annie while she is alone and she "performs for Ryan over the phone. Does she feel any remorse over that? You never know.
2. If you confront Annie about Martin and she answers truthfully she seems to feel bad about hiding it from you and requests that you talk the next night. She then goes to work the next day admits to Martin that the MC knows but then gladly screws his brains out.
Now compare that to the MC when both Chloe and Emma admit they love him. He flat out tells them sorry but I'm with Annie. That is my only concern. [ . . . ]
All I know is hearing her thoughts and dialogues in the Spicy Mod made the game objectively better.
I don't know if it would have the desired effect of making her more likable to her critics, though
Actions speak louder than words.
This is a story about a couple told through the MC's point of view. We do not need to see Anne's POV to develop or change our opinion of her behavior. It is not necessary to hear Anne's thoughts to know that she enjoys doing what she is doing.
Hearing Anne's inner dialogue, as you pointed out, will not please the majority of people who think Anne is off the rails. Hearing that she is enjoying her sexual encounters, or worse — that she is becoming romantically involved with certain characters — works to further push her into the unlikeable character.
The two examples you gave are excellent examples of why she is no longer likable. A wife feeling remorse would not perform for Ryan after her husband, who she is supposed to be tremendously in love with (according to the story), confronts them and throws Ryan out! And a wife that loves her husband and regrets not telling him about his dad secretly hiring her is not going to then go and screw that father's brains out.
My favorite scene was how fucking disappointed she was with the tattooed guy she met on the beach.
Using the Spicy mod does not change her behavior, or excuse it. You do get to see what her opinion might be on certain "adventures." For example, the white guy at the beach and not being happy with his performance. That doesn't change her behavior.
I think if we are looking for a quick fix button, it would be adding the option to not participate (Anne and therefore the MC) in each sexual event (WITHOUT Anne getting angry). One event the game DOES do a good job of this is with Dre. You can choose to include that storyline or completely omit it.
