My thoughts so far...

I second and third the variety point. The fact that you and I almost never agree on what levels we like is a GOOD THING. In the original CC it never seemed like you were playing two similar levels (except TOTALLY UNFAIR -- and that had a point.) We need to strive for that kind of variety. We don't need super-complex levels like those in CCLP3, but we do need to present the player with all the vast possibilities available from what is really a pretty small starting set of game functions.
