[Haskell-cafe] Simple game: a monad for each player

I looked at the operational package (since it seemed simpler).
I see its interest when building sets of operations.
I think I see how I could apply it to my current problem. I saw in the
tutorial the sentence: "The ability to write multiple interpreters is also
very useful for implementing games, specifically to account for both human
and computer opponents as well as replaying a game from a script."
So I'm supposed to write 2 functions, one interpretHuman (running in IO, and
prompting the user), and one interpretAI (running in Identity)?
Are there examples of such games using operational?
