Remaining practically identical to its predecessors, with the addition of Pikachu and the ability to obtain the three regional starters in this adventure, Pokémon Yellow is just as fun as the other two games. The Pikachu that follows you and reacts according to its mood adds a special charm to the game. However, aside from the happiness system, which would be further developed in Pokémon Gold, it is more of the same as Red and Blue.
