But I do have a system I enjoy greatly. Read that back! I also enjoy discussing technical merits on forums and try to avoid the subjectives because its down to individual interpretation.

Your not going to find an answer to your question because it clearly means different things to different people.

I've given you my answer for what makes an involving system for me. I think your just looking for affirmation of your own beliefs on a moving target here because your not listening to what I or others are saying.

What your essentially trying to do is unify 'religions'.
