But unlike some of its peers that support multiple gaming platforms, GamerOS only focuses on Steam. GamerOS, as you can probably make out from its name, is a distro designed for gaming. It also scores over Drauger for using a customized instance of the intuitive Ubuntu Ubiquity installer. The distro also includes a whole set of regular desktop productivity apps to pitch itself as a very capable desktop distro for gamers.
The highlight of the distro is a set of optimizations known as GameMode that tweaks the installation to make it more suitable for gaming. The distro also includes the DOSBox emulator to run DOS games as well as ScummVM to run classic adventure and role-playing games. However, with Ubuntu GamePack you also get a time-limited trial version of CrossOver, which is a proprietary compatibility app based on WINE that you can use to run Windows games (and apps). Furthermore, in addition to proprietary codecs and drivers, Ubuntu GamePack also provides multiple gaming platforms and tools including Steam, Lutris, PlayOnLinux, and more. Both distros are based on Ubuntu 20.04 LTS, though Ubuntu GamePack uses a customized Gnome desktop environment.
Ubuntu GamePack comes from Ukrainian developers UALinux, and is very similar to Drauger OS.
