I think you are giving him way too much credit. Chris, or CIG, are not perfectionists. That is just their excuse for their inability to deliver. I would argue that what actually applies rather well to CIG in general and Chris Roberts in particular, is this Oscar Wild´s quote instead:
“Ambition is the Last Refuge of Failure”
Chris is an editorial perfectionist. He expects all under him to deliver what he sees in his mind, but either can't or won't communicate his vision effectively, so he approves something, then thinks of something he wants changed, and has it re-done to chase his vision, even though he couldn't make what he sees in his mind's eye himself.
He is an epic jackass who has stumbled on a combination of a golden goose and a gullible fanbase, though, so nothing more really needs to be delved into in much detail, but I just had the thought and put it out there.
