With a completely new graphic engine in PCM10, Cyanide has apparently felt the need to optimisize their Stage Editor which has pretty much remained unchanged for several years.
In a post on on the Cyanide forum, Cyanide presents some of the new features of the editor. I'm not much of a stage maker, so I'm not fully aware of what's huge changes and what's not. But based on the reactions so far, the new stage editor is a step forward.
Anyway, in short, the new features seem to be a higher grade of control. If you want to move the finish line, move it. If you want to move a specific house, you can do so. If you want to make your very own turn design, that's possible too.
And for the non stage makers? Well, there's a couple of screenshots of the stage editor in action - and although they aren't all that interesting, they are, after all, screenshots of PCM10 ;)
