I really hope this isn't just Arch with a skin on it and some settings changed. They seem to really understand Linux, to the point where they have submitted kernel level changes and enhancements. It is packaged for Debian in the non-free section. Starting in 2012, it has official support for GNU/Linux, and has a custom version of Wine included for running Windows-only games and software.

Valve has been a Linux contributor for a long time. Steam is a proprietary content delivery and launcher application for video games, creative tools, and multimedia such as movies and soundtracks. Is it really a full distro based off Arch (similar to Manjaro, or how Ubuntu is based off Debian) or is it really just Arch Linux with a couple tweaks and a KDE Plasma Desktop interface that boots directly into the new big picture mode. What I want to know is, HOW different is SteamOS from Arch Linux. SteamOS 2.0 was based off Debian, SteamOS 3.0 is based off Arch Linux. I understand that Manjaro for example is based off Arch Linux.

Then there's distros that are based off of THOSE such as mint or pop!_os being based off Ubuntu. Then there's other distros that are still considered core distros but are based off the real 'core' distros like Ubuntu. Most Linux distributions are variations of other distributive.
