are choices even matter (except some obvious ones like alley scene or first scene stand with nick or other guy)
for example on the professor scene tried opposite ones but didnt change anything, there is bunch of choices like this all over the game
Yes! I'm glad you asked because we're going to make this more obvious in upcoming releases.
1. Regarding the choices during the scene with Johnson- Yes, these choices will have a significant impact on Part 2 of Episode 2. Unfortunately when we decided to split the episode up it left the Johnson scene hanging out there on an island a little. We thought about making changes to the episode for more immediate payoff, but they often were going to require additional development time and we didn't want to go down that road. If you pay attention to the Freak Scale, you'll notice that the various choices influence how many (or if) Freak Points Emily gains. Depending on where Emily is on the Freak Scale, that will automatically trigger certain paths in part 2.
2. The ending to Episode 1, and the sex scene from Episode 2 part 1, are all dependent on the Personality Spectrum score. Depending on if Emily is on the Generous or Independent side of the spectrum dictates how those scenes playout.
3. This is small Easter Egg, but the choice you make in Episode 1 about which picture to send Nick is referenced in Episode 2. That picture will continue to play a small role going forward.
4. Choices made in the very first scene of Episode 1 dictate how the very next scene in the cafe plays-out.
I suspect that we've made these branching paths a bit too subtle and that people don't know they're missing content.
