simplest explanation is that it’s for people who want to game on Linux and use Linux with minimal configuration and tinkering. It just has a lot of sane defaults like:

• Nvidia drivers and Steam pre-installed
• Flatpak for apps (installing packages is discouraged since doing so recklessly can break your system)
• “immutable” core (this is harder to explain but basically it makes it very hard to break your system)
• background updates with easy rollback in case something goes wrong (just be warned that by default you can only rollback to the previous state, nothing older than that)
• Wayland
• advanced tools in case you need them (podman, distrobox, ujust scripts, brew, DX mode)
• active community to provide help and support
