Wonderful game, I (personally) would enjoy a sandbox mode where you can just mess around and/or edit NPC appearances
Turn on debug mode in settings and download the BOOP mod. Debug allows you to spawn items and change variables for quests and events, while BOOP allows to you to edit NPC models.
I uh, can't seem to find it?
Debug is near the bottom of the "Game" tab in main menu settings.
Boop is spelled B.O.O.P., my mistake. It can also be easily found in the built in mod browser by sorting the list by name.
