Emits
Weather and ambiance
ringing the hours
Swap day and night descriptions for nocturnal creatures
PCs out and about when it’s not their daylight cycle have reduced vision.
Add scent and sound descriptions to room descs
Have day and night change more frequently than in RL (i.e. one hour RL time is two hours game time. This will allow players from various time zones to be able to experience day and night in the game.)
Food
Any PC can eat whatever they want. But to heal they need to eat X of their 'type' of food, i.e. horses need to eat vegetarian food during healing (Could also make it so they heal faster if they do, but don’t require it).
