PTS Games - PTS Games began as a private server project in 2011, originally just for friends and family. What started as a fun way to play games like Ark: Survival Evolved and Conan Exiles soon evolved into a public gaming community after an accidental server misconfiguration attracted unexpected players. Since then, PTS Games has grown into a welcoming space for gamers to connect and play together.
Stop Killing Games:
"Stop Killing Games" is a consumer movement started to challenge the legality of publishers destroying video games they have sold to customers. An increasing number of video games are sold effectively as goods - with no stated expiration date - but designed to be completely unplayable as soon as support from the publisher ends. This practice is a form of planned obsolescence and is not only detrimental to customers, but makes preservation effectively impossible. Furthermore, the legality of this practice is largely untested in many countries.
