Walkthrough No. 3 Fire Emblem: Awakening, Train Your Team!

The Walkthrough:
This isn't going to be a complete walkthrough as the game tells you what to do mostly, this will focus on recruitable characters, DLC and the like:

Walkthrough No. 2 Animal Crossing New Leaf - 3DS (7+)

This walkthrough is a walkthrough in the loosest sense. As Animal Crossing isn't a game you can walk through (is it even a game?) so I suppose that this is more than a tips and tricks section more than anything. But in the interest of keeping the amount of different types of things we do to a relative minimum I'll call it a walkthrough.
Warning: spoilers, obviously.

Walkthrough No. 1 Mario Kart 7 - 3DS (7+)

Warning: These next paragraphs contain all the best tried and tested cheats for Mario Kart 7. So be warned.
