There's another engine starting with 'X' (something like Xenon) which was open sourced recently from a commercial studio which might be worth looking into too.

Two other engines which might be worth a look are Banshee ( https://github.com/BearishSun/BansheeEngine ) and GamePlay ( https://github.com/gameplay3d/GamePlay ). Has anyone here taken any of these for a spin?
