World-building (non-main storyline, fleshing out the world of the game)
Plot-based (main storyline developments)
Character development (fleshing out the characters and their motives)
Custom sex scenes (cutscenes almost purely for unique sex events)
Comedic-themed scenes (light-hearted, comedic stuff)
Dark-themed scenes (gritty, fucked up stuff)
Easter eggs/unconventional cutscenes (things like the Spiderbot cutscenes in this build or Faye's "upside down" cutscenes)
