while agree with darkinferno's #314872,

it could be easier(take less work) to get pass with unity. Though this highly depends on the person, if you know the limits and the workarounds of a7 you could end up with a better product with a7.

For a7 engine, even if it is not feature-rich as unity3, it is not bad - just the editors are too old. Lite-c is the main better part for me when compared to Unity, but having an editor like the one on unity can be more charming after some point.

MED is quite a good tool for importing and tweaking, it needs a interface polishing and more format support.They can focus on importing rahter than editing for MED. (more formats etc.)

WED could be completely dumped and a new editor can be written.

SED is not bad but looks old, i remember editors like LED on some threads it could be included instead.

For the engine itself, a better renderer can be better.

I donot know why JCL is not doing this but using open source tools or parts of them. it could decrase the need for the manpower. Like UV unwrap tools of blender(see Road Kill ) for med, or a proven Renderer.
