If you're interested in doing the public arcs for characters I'd recommend having a save dedicated to that as each branch is exclusive.
Actually you need at least three saves (or sets of saves) because several important characters can only be unlocked from India's private route:
- Private routes for all characters, split routes (private) for Romi and Elliot
- Private route for India, public routes for all other characters, split routes (public) for Romi and Elliot
- Public route for India, joint route for Romi and Elliot, ignore most other characters
- (optional, rather short) Macro/bimbo route for India, ignore most other characters
I recommend that you "Save to Disk" and use a suffix in the file names to distinguish the three or four sets of saves. For example: "sluttown-usa-...
-all-private.save", "...
-all-public.save", "...
-india-public.save", "...
-india-bimbo.save" or other variants.
To create these sets of saves, you can start a new game and do the usual grind until you are presented with the public/private choices for a character. Then go back a few steps (back arrow) before you started the scene with that character, and focus for a while on other characters. After a while, you will have a game in which India, Karlee, Jessica, Gia and others are at the point where meeting them requires you to choose between their public and private routes. Save that to disk (maybe give it a suffix such as "-common" or "-initial-choices" before you start forking the routes).
Note that you will not have met Veruca/hacker, Leah, Veronica and many others (Joanna and her friends, all strippers, all pornstars, etc.) because Veruca can only be met after selecting the route for Romi and Elliot, and all others can only be met on India's private route (some of them require going rather far: Veronica and Penny will only appear after step 26 on India's private route). A future version of the game may allow the other characters to be unlocked on India's public route, but that is not possible yet.
Then you start forking by keeping one set of saves in which you select the private route for India and another set in which you select her public route. The first set can be split further by selecting the public or private routes for all other characters. Remember to use a unique suffix for each set of saves so that you do not mix them up.
This will give you three or four sets of saves that you can go back to whenever a new version of the game is released.
It may be a bit frustrating to start a new game from scratch in order to be able to create these separate sets of saves, but it is well worth the effort. The sooner you create your saves for private/public routes, the more you will enjoy the future updates of the game.
When the Changelog for 0.48 announces a new set of scenes for Romi's public route, you can load the latest file with the suffix "-all-public" and have your fun with Romi. Once you reach the end of the updates for her story, you save a new file with the suffix "-all-public" so that it will be ready to be used when a future version of the game has more updates on a public route for Romi or for another character. The same Changelog for 0.48 announces some updates for Khloe's private route, so you switch to your latest save with the suffix "-all-private" and you enjoy Khloe's craziness. You can also enjoy Meana, because unspecified routes should be considered like private routes until there is a choice between the public and private routes for that character. Consider these sets of saves as some parallel universes between which you can switch whenever you want to play some public or private routes.
