Can I Run Garry's Mod?
Released in 2006, Garry's Mod is a casual indie game built by Facepunch Studios. Publishing duties went to Valve. The game supports a single player campaign and cooperative play. Cloud saves are enabled. Workshop content is supported, so the published requirements describe the unmodded game only. It is localised into 31 languages according to the store listing. It carries 29 achievements. Builds exist for macOS and Linux as well as Windows. With more than 1080 thousand player reviews on Steam, its behaviour on real hardware is well documented. It is old enough that no current GPU generation existed when it shipped, so modern hardware tends to be far past what it can use.
