I have quite mixed feelings about it. I started playing Summer with Mia 2 before part 1. I really liked swm2 so far, However this game is just a porn game. It has great animations and models especially for the time it was made.The characters are cool even though mia looks a bit doll like. emma is great,her character and plotting is a strong side of this game. However the story is uninteresting. Besides emma's plotting , the story is basically just trying to get laid and then fucking and being more and more depraved. Only at the very end mia develops feelings for mc and wants to stop what's she's doing. She starts thinking about future but finds out that mc has a romance with their mom. She leaves to start a new life away from mc and their shady past. Thats the part when story got interesting, her finding out about everything,last interactions with mc,last sex with mc,and first romantic one, and then goodbye letter. The letter was really good and last interactions between mia and mc, her not wanting to hear how he feels about her,cause she knew she had to leave,that was great. But overall in my mind part 1 is just an intro to swm2. The story of 2 terrible people engaged in blackmailing, harrasment and so on led by their even worse friend emma. Then they start developing feelings and Mia is betrayed, both by her brother and her friend. she realizes that she has no one she could count on,and they are on bad path. she then leaves to start anew,leaving mc the money they made doing porn to help him star a new life as well. She writes a letter to mc explaining everything and expressing her wish that they both would become good people in time. That's really it and i wouldn't mind this kind of explenation in swm2,and then you wouldn't have to play part1
