Pokémon Stadium was released in North America in 2000.
The Nintendo 64 strategy game had already launched in Japan in 1999. It featured 3D, turn-based battles using the 151 Pokémon from the Game Boy games Pokémon Red, Blue, and Yellow.
A bundled Transfer Pak let players connect compatible Game Boy cartridges to view, organize, store, trade, and battle with their own Pokémon. The game also included four Cups, a Gym Leader Castle, and a collection of mini-games.
The North American date is easy to confuse with the Japanese release or with the Japan-only Pocket Monsters Stadium from 1998. Pokémon Stadium reached Australia and Europe in 2000 as well. Its sequel, Pokémon Stadium 2, later expanded compatibility to Pokémon Gold, Silver, and Crystal.
