This project aims to fix most of those issues and offer a better gaming, streaming, and content creation experience out of the box. Some of the important things that are missing from Fedora, especially with regards to gaming include WINE dependencies, obs-studio, 3rd party codec packages such as those for gstreamer, 3rd party drivers such as NVIDIA drivers, and even small package fixes here and there.
A typical point and click user can often struggle with how to get a lot of things working beyond the basic browser and office documents that come with the OS without having to take extra time to search documentation. Fedora is a very good workstation OS, however, anything involving any kind of 3rd party or proprietary packages is usually absent from a fresh install. The Nobara Project, to put it simply, is a modified version of Fedora Linux with user-friendly fixes added to it.
