I spent almost a year with attempts to create or choose fitting existing engine. After dozens of engines I had been trying, I found Shiva3d. Its set of features and supported target platforms is amazing and I've not found better price/value ratio tool. Even if I usually prefer freeware/OS stuff.
(note: in my engine choosing process I ignored all engines which utilize only low-level languages, due to my python roots)
