I was waiting for the patch to drop and kinda forgot about this. Just played the last update. This MC on the dark routes cracks me up. That rickroll at the end lol.
I just realized why the humor in this game is so funny to me. It uses the Seinfeld/IASIP style of comedy. Basically, all the NPCs are normal people that behave and react to situations more or less in believable ways. The joke is that the MC is a sociopath like the main cast of those sitcoms. We see this obtuse, narcissistic, psychopath interact with normal people, and that generally leads to some great dark comedy. Of course, there are some colorful supporting characters apart from the MC, as is the case in the shows, but most of the LIs are normal people.
