Pokémon (video game series)
In 2010, Pokémon HeartGold & SoulSilver were released. They did not take place in a new region, or have any new Pokémon. They were simply remakes of Pokémon Gold and Silver. Like Pokémon Yellow, the player's Pokémon can follow them. The games come with a pedometer like device, called the Poké Walker, that can let players walk with their Pokémon, and gain Watts, which can be used to fight Pokémon, or dowse for items.
