Oh I understand and expect the engine to evolve- when I say 'complete' I'm refering to advertised features. Not some far planned feature only listed far in a beta document but rather those listed on the front page.
Intense X may be 3rd party but that doesn't qualify it as an example to throw out. It's waiting for a basic standard set for panels and so on- not some new shader implimentation.

This is basic game setup stuff we're talking about. Stuff that really should be established and in place before the engine is even presented.
