Couzoids

What's the only thing in the great that looks poor? The launch. No smoke/steam clouds (or dust on the Mun) shooting out from the pad. No fire shooting out of the flame trench. Not even a radial glow on the ground from the bottom of the rocket on Kerbin or the Mun. All of these could be fairly easy graphical updates that would really improve the experience IMHO.

An improved game engine with better graphics (landscapes, particles in particular) and physics. Can't help but think the Unity engine is holding back a brilliant game from being utterly fantastic.
