I have seen multiple people take this perspective. First, it's difficult for me to believe you'll really enjoy Allison's scenes if you can't find any other scenes interesting. Not impossible, just unlikely. Second, you plan on waiting to play Part 1 and Part 2, which you already know don't have sexual intercourse with Allison, until you hear that some later part does. Thus placing unnecessary delays in your path once you can have "sex with Nana". You know, when you can get the "bad parts" out of the way, making the time between that eventual scene being released and you being able to see it that much longer.
To each his, her, their, or whatever own.
