Yes. Unreal is the most popular non-proprietary engine for AAA by far.

  Isn't Unreal source-available proprietary, as opposed to non-proprietary? I may be wrong, it's been a while since I looked at engines.

    Correct. Source-available proprietary. https://www.unrealengine.com/en-US/ue4-on-github https://www.unrealengine.com/en-US/ue4-on-github

    Non-proprietary in this context is generally understood to mean "not an in-house engine" Like how EA has Frostbite that's only used for in-house titles

      Ah, that makes sense. Thank you for the correction!
