2 saves, 1 for mia etc path and 1 for sadie etc path.
While I can now appreciate Sadie, I was always invested in SWM1 & 2 because of Mia and of course the wincest. While I was bummed how SWM1 ended and in my game, it was Laura who ended things with the MC, I really liked the focus on developing a love story with Mia after all that time apart.
That said, I doubt I will start over and play other paths. Isla and Cindy were very tempting, but being a romantic at heart, I prefer Mia over everyone else, except maybe Grace and Laura. The Vivian - Sadie threesome scenes were...interesting, but not sure how that path will pay off since Viv is...well... gay, and seems allergic to being in a relationship again. The only possible outcome I can think of is if we ultimately reject Sadie after said threesome, I guess it's possible she finds comfort in the arms of Vivian as her new girlfriend? Either way, it's not a path I'm willing to continue exploring, along with Giselle's path. Both were fun initially, but had to end them both.
