Well, if you want to be great in the eyes of the Great Moustache (or anyone not into so-called banalities, really), the first thing is busting your own ass outta the orphanage (which functions more as a child brothel, because reasons). How you do so presents different opportunities. I mean, what's greater than starting from the bottom?
The Hunter route could go with something a little dark or brash, which introduces the player to a facet of the world 100% based on the culture of death.
Bargaining your way out (at the expense of your fellow orphans' lives ;n;) will introduce the player to something called corruption and sacrifice for the greater good (politics).
For the third route, it could be anything.
Because honestly, while getting the whole city to fall apart on the second page is entertaining, it's not climactic.
