Would it be possible to create a few npcs that will randomly walk to you out of nowhere, and ask you to do certain tasks for them?
Just an idea of a system for quests, that aren't repetitive, and can have more quests added later on, without creating a new system.
They ask you, and you can reply, yes/no.
They are randomly timed events, only you can see the npc.
Example quests/tasks that npcs may ask:
Example Quest 1
"Hello traveler, my (insert relative) is sick, I need medicine. Could you please collect (insert insect) and talk to the witch. I heard she can make potions to heal."
(Yes)
Thank you, please hurry!
(No)
Well f.. im jk.Oh, what a shame, I guess misjudged you. Look's like there is no hope for my (insert relative).
Example quest 2
"Help, someone stole all my bait, could you please collect (insert worm amount)."
(Yes)
Thank you, I can finally eat

.
(No)
I guess my family won't have their meal again. This will have been a week without food
Ex 3
"Could you by any chance collect some slime spoils, I heard it does wonders for your skin"
(Yes)
Thank you, now I can finally ask (insert person) to have a drink with me at the pub. (Probably not drink for the majority...)
(No)
I guess, I'll stay ugly forever...
4
"The baddies are planning an attack, here is a map of their location. Please put a stop to them"
(Yes)
You receive the map, and have x amount of time to take out the baddies.
(No)
I really thought you were the one...
