My game already has tons of branching choices even though it's just the first release, if you stick with the choices you make and don't roll back things play out differently.
It's not linear. Based on dialog choices the story will play out very differently and it will end differently. This doesn't mean just that the main female character will have different outfit because of your choice, that bullshit is what I noticed people call different path these days lol. No, different paths and story lines mean that the story will take a turn and it will play out differently with new different characters. In one path some characters will die, in another they will remain alive. You will also end up in different regions, you might even end up living in Meteor Valley, and not in your home city. I don't want to say much cuz, spoilers...
The MC's life will shape out differently as well, he can settle down and start a family and get married, or he can choose to fuck as many women as he can, he can go broke, homeless, or get extremely rich. One choice doesn't decide which direction the game goes. For example if you choose to pursue Lexa, the game can turn out very differently if you chose to settle down with her. You might not even succeed, since previous dialog choices with her will decide the outcome of it, if you mistreat her. emotionally hurt her or straight up you're an ass towards her she will leave you etc... All characters have their own personalities, they are not just brainless bimbo's (except for Kelly lol) they all have their own minds and they will react to your choices according to their personalities likes/ dislikes etc...
There will be 5-7 chapters total, as many as I need to finish the story. But I don't think it will be more than 7. And since not everything is written (I recently begun writing chapter 4) I don't know how may female characters will be in it. Different paths and regions have entirely new main female characters, and side characters.
This is very difficult for me to write it all down in words because I'm so far ahead of writing and from what I released so far, that I have to be very careful about what I say so I don't give out major story spoilers, so lots of times these ramblings of mine doesn't make sense, but I hope this somewhat satisfies your curiosity lol
