San Francisco (CNN Business) Nintendo knows how to capitalize on a successful game.

On Wednesday, the Japanese gaming company announced the launch of two new Pokémon games on its Switch console: Pokémon Sword and Pokémon Shield.

The move is a sign that Nintendo is trying to use adaptations of old favorites to breathe new life into its Switch gaming device.

Nintendo has responded by giving the people what they want — the classics they fell in love with years ago.

"Pokemon is absolutely their sweet spot," Pachter said. "They'll sell 12 to 20 million [games]. It's something that Pokédads will buy because they remember and love the Pokémon brand."

Pachter told CNN Business that Nintendo has at least 30 different brands, including favorites such as the Mario, Zelda, Pokémon and Super Smash Bros. franchises.
