One-time event or not, CN will undoubtedly think Live-Action is the way to go.
It probably is a one time thing too, but take this for example:
Say you went the same way to school everyday for 10 years and nothing happens, but when you take a second route to school for the first time in your life, you find a briefcase filled with $1000. You're going to keep going the second way, regardless if you find anything else, based one a one-time, spectacular event.
That how I think CN will see it.
