IS there a way to add time limit quests, or to the game or in anyway limit/restriction the rest function by using the mod tools?
Amii was more 'event - limited', but yes, scripting supports the use of game time. Resting can be restricted as well by modifying random_encounter.py in the can_sleep section. IIRC you're a fan of having a limited number of rests, should be doable.
