pretty sure this was asked before but i searched and couldn't find anything, do the choices made in the beginning, boob size, slim/fit, etc do matter in the choice you get in the island? specially the 2 girls you choose, do they matter or its a way to grab another character that with the previous choice you wouldn't get?
I try to explain how it works again. I'm sure I did somewhere, but cannot find it myself. Maybe it was on da.
Each one of the girls has certain stats (height, breast size, body type).
Based on your preferences, the game assigns "points" to the girls. E.g. for a perfect match in breast size the girl gets 2 points. For a close match 1 point and so on.
The game sorts the list of characters by points.
Then the girl picking to populate the island starts.
Plane girl will always be one the island from the start.
Your 2 hand selected girls will always be on the island (maybe not from the start). They also get extra points for beeing hand selected.
Now the game tries to find a doctor from the list sorted by points. After that it tries to find a masseuse. The rest of the initial island population is random from the girls that have at least 1 point. Everyone with 0 points won't be on the island. Except you manually invite her later in the game.
