Animal Crossing
Here’s the obvious one, and a world that already gears up for the holiday season every year. The quaint villages of Animal Crossing are the perfect time for its critter inhabitants to get together and celebrate. You can set up a holiday display in the town center, with a tree, some holiday character displays and lights all over everything.
Of course, presents are expected as your neighbors will want to give you something special, and expect something in return. Make sure you get them something they like. Everyone can gather together to roast chestnuts over an open fire, and build some snowmen. Make sure you get all those Nendodroids decorated with some holiday spirit too. It truly will be peace on earth, until you don’t visit those animals for a year and they think you’re dead that is.
