Killer 'Wave Bots should be an endlessly frustrating puzzle for those who actually try to put 'em together. The scary looking chromium skeleton Decimator will wander away to paint landscapes or flower arrange or run for mayor of Titan. It would be funny to have a would-be evil organization completely and fruitlessly locked-in to making their death-machines actually want to kill. Mischief should be possible in order to allow for a certain fun level of deviltry. Fen-Space villains  should be allowed certain operatic boons : platoons of minion bots designed for Skeletor's Main Street  parade or for acquiring an obvious 'Steal me, villain!' gimcrack.  The key thing to remember, as far as I'm concerned, is that Fen is inherently not serious. It's, 'Geeks in Spaaaace!' It's LARPing writ super-large. With that in mind, killer robots? Giggle.
