Can we even compare utilons across agents, i.e. how can we measure who fulfilled his utility function better, and preferably thus that an agent with a nearly empty utility function wouldn't win by default. Such a comparison would be needed to judge who fulfilled the sum of his/her/its preferences better, if we'd like to assign one single measure to such a complicated function. May not even be computable, unless in a CEV version.

Maybe a higher-up can chime in on that. What's the best way to summon one, say his name thrice or just cry "I need an adult"?
