New York (CNN Business) The "Pokémon Sword" and "Shield" games are getting new adventures, cuddly creatures and rivals to battle. But Nintendo isn't adding the content for free, and some fans are upset about the cost.

Fans will have to pony up $29.99 for an expansion pass. That's in addition to $60 for each original game. An optional online subscription service costs $19.99 per year.

Pokémon enthusiasts who want both "Sword" and "Shield" expansions will have to pay about $60 in total. New content is coming in June, and more will be added in the fall.

"It's a pretty steep price for a full Pokémon experience," Kori Selnes, 29, a Twitch streamer in Norway who has played Pokémon games for more than 20 years, including "Sword" and "Shield." She told CNN Business that she "used to love the franchise to bits, but the direction it's going now makes me not want to support the companies involved anymore."

Game Freak, which co-owns Pokémon with Nintendo, said in a Thursday announcement that it was the first time Pokémon games were getting a digital expansion instead of being released as standalone games. It's a new strategy for the franchise, although it has already been adopted throughout the video game industry. For example, Nintendo itself has sold expansions for the games "The Legend of Zelda: Breath of the Wild" for $20 and "Super Smash Bros. Ultimate" for $5.99.
