Exciting games for consoles I don't own

Oh my god you guys.
A new Tomodachi Collection comes out next month!!

THEY BREED. And do so many... THINGS.

There can be love triangles! And hats! And the children actually grow up!

It's for the 3DS... which means that I now have two games I want that I can only play if I buy a 3DS, this and the new Animal Crossing....

I wonder how much a used 3DS is...
