Nintendo is finally bringing its popular Tomodachi series westward with Tomodachi Life, a sim that uses custom Mii characters to develop the story. It will be coming to 3DS on June 6 for $34.99, the company announced today.

Tomodachi Life has you customize your town's inhabitants by making Mii characters for them, including traits like their voices and personalities. From there, they'll take a life of their own based on how you've defined them, and interact with the other Mii characters. You then advance the plot by exploring their island and helping to solve their problems, and snap and share pictures of their exploits. Your Mii characters can come in contact with celebrity Miis as well--Nintendo has announced that singer Christina Aguilera will be available (in Mii form) at launch.

"Nintendo fans are familiar with Mii characters, but now they come to life in ways they never have before--with their own lives, interests and personalities,” said Nintendo of America marketing VP Scott Moffitt, in the announcement. “Customization and open-ended play are two big video game trends for 2014, and Tomodachi Life delivers a fun, creative experience that makes you want to visit again and again, because there’s always something interesting going on.”
