I think the best choice is not let that What if scenario could live at the same time, the mind of the main char must no be nearly right even in this types of games or just lose all the credibility (repeat, the credibility that can have in this types of games)
i like how the alternatives of do the right chose are more wored and funny in the lates episodes, but I will maintain just in that, maybe some more elaborated, but not two paths living in the same walk, too much work , effort and dificult while the game, for me, is nice the way it is already.
If i have to chose something to add will be something like protec all and just only have sex with one, but this already will need so mucho work for worth just choose one.
