I keep seeing threads about people resetting to get different characters/plots. I've not a clue what it means and why you would do it but I need in on the action!
Usually people plot reset for villagers they've adopted in order to get them into desirable spots as to keep the town organized and/or not to destroy paths/flowers.
Villagers are scheduled to move in on certain days when you have only 8 villagers or less. For example, the day after you start the game, a villager moves in. Two days later (I think), someone else moves in. When you know what day a villager moves in, you can plot reset to get good villagers, although it can take forever.
To plot reset, people load their mayor on the next day at 5:58 AM, then save and quit. They wait a little bit and then make a new character. As the character, you can look around to see who's moving in. If you don't like them or their house placement, you can simply press power and try again. Plot resetting won't mess up your town and Resetti won't yell at you. When you find a villager you like, you go through the normal steps of choosing where your house is and such. You save and quit when you're allowed to and then load up the new character to delete the house (unless you want to keep the character). You can't plot reset if you already have four human characters in your town, however.
The two comments above me sums up your question quite nicely. It's a method people use if they want to keep their town nice and tidy. Who the heck wants a villager moving on top of their flowers or path works? Haha!
That too haha! I actually just got done forcing a villager to move out of my town that was blocking the area where I was trying to build a bridge. It's strange that villagers can move close to a bridge and if you tear that bridge down to construct a different model of one, you can't because the villager is "too close".
Thankfully I have seen that happen, but already knew that a villager was coming in on that day and prepared for it. But yea, that usually gets me pretty aggravated.
