Sometimes the AI in a videogame has lots of perfectly valid actions it can take, but deciding which one can be quite difficult. Utility AI is one approach to help solve it, by calculating how useful that action is based on the current context. We look at how it works, some simple calculations and how games ranging from @electronicarts's 'The Sims', all the way to @CreativeAssembly's 'Total War' series, adopt Utility AI in their games.
