Here's something I always thought would be nice in the AC next games.

After played hundred of hours, when I feel that I can't improve my town more that it is already, I feel the game becomes a little bit redundant. I always thought that making 'little stories' could make this game replayable and fresh.

Let me explain the concept.

Times to times, Nintendo could release DLC that strigger an event in your town.
-A sort of murder and mysteries (no violence for sure! find wich villager stole the cherry pie!)
-A love story (prepare a blind date between two villagers, celebrate a wedding)
-A friendship story (reconciliate two villagers, have a tea party with you villagers)
-etc.

The characters of the story are chosen in your villagers and the NPC. You have to accomplish some tasks to complete the story or solving the mystery and this earns you a very unique item that you can expose in your house or in your town.

That could change a bit from the : can you bring this to him/her? again and again quests, because the story would last a couple of hours and would permit extra tasks that you don't do often.

Tell me what are your thoughts about this!

I think this would be a great idea! It would help make each town extremely unique, and would help give more personality and background to the characters. It would be neat to start up your game, and maybe you would walk out to Isabelle doing the distressed emotion, and she would then tell you about a villager stealing a pie and then youd have to figure it out. I think AC could use some new dialogue. My town is actually getting a bit boring as well, ive completed a lot.

Thank you for your reply! I don't believe this will ever happen some day, but who knows? That would be fun!

Maybe xSeed or Level5 could make an AC spin off?  Actually- there was one already made that is similar to what you described, it's Magician's Quest Mysterious Times.  Unfortunantly the 3DS version was never brought to the U.S., but the DS version is fairly cheap and easy enough to find.

It's a great game, definitely worth trying out.    I totally agree with you though and I'd love to see something similar to that brought back to NA.
