It’s hard to believe, but Pokémaniacs have been trying to catch 'em all for two decades. Nintendo and the Pokémon Company are celebrating the 20th anniversary of Pokémon with a year full of new products, re-releases and huge doses of nostalgia around the world.

Up first is a re-release of the very first Game Boy games (“Red,” “Blue,” “Green” and “Yellow”), which will be available for purchase on “Pokémon Day,” Feb. 27, exactly 20 years since their initial launch. Trainers can download digital copies of the game for their Nintendo 3DS or 2DS, or they can buy a special edition of the Nintendo 2DS.
