Inconsequential?
It's the actual challenge the MC has to complete that the title of the game is named after...
As I mentioned in my other post- there is most likely (hopefully) a reason why they all take the challenges so seriously
Yes, inconsequential in the current game, as in less than 50 lines of script dedicated to any reference of mothers and sisters out of nearly 40,000. As in 0.01%.
That's not to say it wont play a more major role in the future, I don't know where the game will go, but the current version spends little time on this, thus my original confusion at the other guy's comment at how donnie was such a bad guy for the challenge.
