Is there anything that proprietary software can do and has no open alternative?

• warzone2100

  122 3,035 9.9 C++

  Command the forces of The Project in a battle to rebuild the world after mankind has been nearly destroyed by nuclear missiles. A 100% free and open source real-time strategy game for Windows, macOS, Linux, BSD+

  

Also Doom itself and various other ID games are fully open source. In addition there is another game, Warzone2100 was re-released as open source by the developers as well. I'm sure there are more games like these, but this all that comes to the top of my mind.

• ArxLibertatis

  29 902 8.6 C++

  Cross-platform port of Arx Fatalis, a first-person role-playing game
