DXX-Rebirth

Installation requires consulting a separate INSTALL.markdown file, which may involve compilation or configuration steps that aren't user-friendly for non-technical players, lacking out-of-the-box simplicity.

Exclusively a port for Descent 1 and 2, so it doesn't support other games or provide a framework for new developments, restricting its utility beyond these specific retro titles.

Users likely need to provide their own game data from the original Descent releases, which can be a barrier if they don't own the games or have access to the files, adding an extra step for setup.

While it adds OpenGL effects, it lacks support for contemporary graphics technologies like ray tracing or high-resolution texture packs by default, limiting visual upgrades for those seeking cutting-edge enhancements.
