After the recent release of their fan-made Pokémon game, both Pokémon Uranium developers removed their game after receiving takedown notices from lawyers working for Nintendo. As seen on its blog post, “we have been notified of multiple takedown notices from lawyers representing Nintendo of America.”
Though both creators of the fan-made game did not share the notifications received, they did remove the official download links for the PC game that was previously available on their web site. “We will no longer provide official download links for the game through our website.” The post also adds that they cannot verify that the download links not located on their site can be recognized as legitimate ones and for gamers to take careful considerations before downloading the PC game “from unofficial sources.”
According to the creators, their unofficial Pokémon game was downloaded more than 1,500,000 times. “We are blown away by the response this game has received, and we thank you all so much for your outstanding support.”
