How do I discover the highest-rated/widely-used (and publicly use-able) recreation engines to make use of for 3D or “Fake 3D” video games? Besides Unity or Unreal Engine?

I’m making an attempt to keep away from opinion by saying “highest-rated” and “widely-used” however I’m not sure of how to take action.

While it’s not possible to foretell any particular recreation engine’s longitivity, I wish to spend my time utilizing (a) recreation engine(s) that can survive so I can keep away from needing to rewrite my recreation in a special recreation engine later.

P.S. I’ve spent a good period of time researching this already, and have encountered info overload. Additional assistance is appreciated.
