Video games, in general, require that we suspend our disbelief to some degree. We can forgive the unbelievable or the improbable so long as the experience remains entertaining. Games are full of trivial details that make no sense -- eating food magically heals wounds, a three-foot tall wall is insurmountable by a grown adult, etc. -- but we overlook these small annoyances for the sake of enjoyment.

The thesis of Amy, based on my experience, is very simple: Take every one of those annoyances and build an entire game out of them.
