Pokémon fans in 15 countries got their first chance to play wildly popular mobile game Pokémon Go over the weekend, but prospective players in China, India, and Korea are still waiting for the title to debut in their own territories.
Niantic confirmed trainer locations on Friday in the following countries: Brunei, Cambodia, Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam, Taiwan, Papua New Guinea, Fiji, Solomon Islands, Federated States of Micronesia, and Palau.
Niantic CEO John Hanke told Forbes that Pokémon Go's introduction in Korea is proving particularly challenging, due to Google Maps' information system being limited because of security concerns over North Korea.
As for China, Hanke called a rollout "technically possible, but difficult to introduce due to the many hurdles, or should I say regulations we'd have to clear to get it to users."
Niantic has been silent on the reasons for the launch hold-up in India, which is home to a lucrative mobile market of over 200 million users.
Meanwhile, Iran's Supreme Council of Virtual Spaces has temporarily banned Pokémon Go in the country. According to the BBC, the ban is related to "unspecified security concerns" and followed a short meeting where the council "were waiting to see to what extent the game's creators would co-operate with them".
The game has been downloaded 100 million times in the U.S. alone, and is reportedly responsible for doubling sales of portable smartphone battery backups as players roam for extended periods trying to locate Pokémon.
Its ratio of paid users to total users is said to be 10 times that of Candy Crush, which generated over $1 billion of revenue in both 2013 and 2014. According to brokerage Needham & Co, Apple is set to make $3 billion in revenue from the game's in-app purchases in the next one or two years.
