Sorry to follow on from your excellent post with my terrible thoughts,Ed.

Robot Wars may well be a brand that comes back and peaks for a bit and then troughs & then plateaus. I don't think it will ever again reach it's 4/5 peak

That is, if it ever gets back on TV at all. Never mind the money, the commissioning briefs never call for anything like Robot Wars. Of the two, Techno Games has better revival chances due to a higher participation rate.
