The name of the game refers to the mc joining the DIK fraternity, not him specifically having a DIK personality.
When it comes down to it, you only have to be a chick or neutral at one point with Maya and Josy (during the library scene where they either accept or reject the mc into their relationship), you can go full DIK after that.
Bella and Sage don't care where you fall on the spectrum, although for some arbitrary reason you can't 69 Bella unless you're a chick.
Jill is the tricky one, numerous times it can be all over with her if you're a DIK. So it's best to chase her as a Chick or Neutral.
Ultimately, since Maya & Josy are a couple, there are really only 4 LI options:
1) Jill Requires Chick or Neutral
2) M&J Require Chick or Neutral
3) Bella doesn't mind
4) Sage doesn't mind
Bonus character:
5) Quinn requires you to be a DIK
(The above assessment is just off the top of my head, so I could be wrong.)
You gotta draw the line somewhere.
Just like you don't download every single game on this website, you just choose the ones that appeal to you.
I erased BaDIK and played it through again to completion, finding everything, unlocking everything, until it was almost 100% complete. I just didn't bother unlocking the Madame's stuff. I have 0% interest in seeing her again.
But I have to admit, when I started playing through BaDIK, I tried everything, investigated everything, went through all the options, including the Madame when she first came out (I'm not gonna say there were no regrets).
But there are other games that I play that I just go down one path and that's it.
What blew my mind was when
dalli_x came out and said he'd only played the M&J route.
