To be cynical for a moment, it's not like the game could ignore the choice even DPC had no intention to offer solo paths for each girl. It would be very awkward, for example, if Maya didn't comment on the first time she had sex with the MC just because he chose to follow Josy in Episode 5.
That said, I agree it's exceedingly likely the option will come up someday.
The mini-games really annoy me because on their own I actually like them. Some are a pain, but overall they do a nice job of breaking up the normal gameplay loop and adding a little zest to certain activities that otherwise feel hollow. The problem is that when I'm replaying the game to try to get to a specific scene, they're a massive roadblock that serves no purpose other than to waste my time.
Fortunately, DPC provided a solution for this, because I could leave mini-games On in my main plyaythrough and turn them off in all my others. I need a gazillion saves on my main, but I could live with that. Unfortunately, DPC botched the implementation of the non-mini-game version because money is
abysmally distributed.
DPC tried to make things simple by doubling the money you find in free roams. The problem is that free roams don't happen at regular intervals, and some never had money in the first place. As a result, money becomes feast or famine; way more than you need followed by far too little in a short stretch. Infuriating.
DPC should have added extra money locations to the various free roams instead, to ensure a more even supply. But that would be more labor intensive on his part, so he probably thought it wasn't worth the time. He was wrong. Hence my DIK runs are stuck with mini-games just so they can blow the money on ale and whores.
