Pokemon Stadium 2 hit the market in North America in 2001, following Pokemon Stadium's debut one year prior. Sticking with the theme of remaining true to the main-title games, Pokemon Stadium 2 introduced the second-generation Pokemon group, including 100 new lovable monsters to the game's roster. The new title also re-worked many of the first generation's Pokemon, revamping their move sets and tweaking their base stats to better reflect the Pokemon's changes in the new game. While some suffered, others rose to the occasion and proved to be reliable compared to the previous game's counterpart.
