Pokemon Staduim is the first to be created for the Nintendo 64 (N64), and has amazing new features, so you can see your Pokemon in 3D! As you

battle it out, play with rented Pokemon, and toss a ring or two around some Ekans, this game is worth trying out, but not exactly a lasting video game.
First, Second, Third's the Charm!
In 1998 (as the very first), it was released in Japan, and lacked what it truely needed. This version didn't have all 151 Pokemon or the required animations for batting the Pokemon, so it was never released outside of Japan. The second version, called Pokemon Stadium 2 for Japan, now had all 151 Pokemon that was shown in the original Gameboy games, such as Yellow and Blue. You could either rent the Pokemon or transfer your own from your Yellow, Blue, or Red Gameboy games using the N64 Transfer Pak. It was critized because of its difficulty. The gym leaders hard to beat; it is usually 50lv againts 50lv. You only had types to help you out against your enemies. The second version (American) was changed to make it easier for the average player.
Whatcha Got To Do

No storyline is in the game, but your main goal is to defeat the Gym Leader Tower, and win cups at the Stadium. Once you defeat the Gym Leader Tower, Mewtwo will show up and battle you; if you defeat him, you are then redirected to defeat the Tower, Cups at the Stadium, and Mewtwo once more to finish the game.
