In Settings menu on the Main Menu
>> Adjustable npc scaling to the player (Difficulty Section)
>> Enable or disable watersports, overstim, etc (Content & Features Sections)
In Encounters menu During Game
>> Ban certain action types in encounters (Limits Tab)
>> Increase or decrease action weights (Goals Tab)
>> Adjust species encounter weights (Species Tab)
>> Change npc sex weights (Sexes Tab)
Caveats
>> Weighting is an imperfect system now that the random encounters are tracked with set NPCs. Increasing npc count will slowly create lag but increase the viability of the weighting system.
>> Exact skill leveling and npc bias catering is not currently in the game. It also doesn't appear planned for either.
Mild Spoiler / Hint
>> Next update should include some ways to change physical aspects of any attackable / fuckable character though most static NNPCs may not have content included.
