I've been quite happy to read the musings on the Zoq-Fot, I just havent had a chance to add to the wealth of knowledge.
I reckon wacky robots is the way to go. Most races are wacky one way or another.
Its funny, after playing SC1 a million times back in the early 90s those cockpit pilots were really fascinating witht their bright colours and strange appendages. Buit nothing prepares you for bumping into Fwiffo when you play SC2 fort he first time. "So that's what a Spathi is!"
Would be nice to recreate that experience with one of the other unused races
