Side Quests

I'm impressed. 

They say that life oftentimes imitates art, but here, this life, I dare say it was anything but an imitation. No, the word we're looking for is perfection. It was the little minute details slid between the gaps of the more major ones that really sold the whole experience beyond the point of just being immersive. 

Sure, you could just slap a fully furnished adventurer's guild made and built to scale in your medieval township and call it a day… just that alone and praises to your name would have still come rushing through the floodgates. 

But it's whole 'nother thing entirely to have a full-fledged chain of command actually running the place, filling out the quest board with objectives and tasks that any passerby was free to undertake and accomplish, along with a row of behind-the-desk receptionists where you could turn in your quests and reap your rewards for completing them.
