OGPlanet was a publisher of free-to-play, massively multiplayer online (MMO), downloadable PC games, based in Torrance, California, with offices in Vancouver, Berlin, London and Seoul. Although their games were free-to-play, OGPlanet offered "Astros", an in-game currency that players could purchase online through Xsolla using a variety of payment methods including credit and debit cards and PayPal; Astros were used for in-game enhancements. On 29 September 2017, the final game being published by OGPlanet, Uncharted Waters Online, was shut down for transfer to Papaya Play and the OGPlanet website taken offline.
