One thing I liked about Grievous was his theme music, sounded a little too much like Harry Potter (which in turn kinda sounds like Schindler's list, haha), but was still very cool to hear when his ship lands on...that planet he lands on. Anyway, I also think it would be awesome if he were gone, but maybe you could reinstate his music elsewhere, cause his theme was the really only interesting bit of music in the whole PT (besides Dual of the Fates of course, which was milked for all it's worth to sell sell sell).

What kind of tools are you using?
