I had the opportunity to watch one of the games on Neil Patrick Harris's show. At some point, he...
...helps a contestant win $10,000 in ½ Off...
...and perhaps not shockingly, he appeared to be having a good time and doing well. Part of his gameplay in his reasoning is using math in deciding real prices vs. fake prices, so it's fun to see someone with a brain that functions on stage playing. I'll be at least interested to see that one, knowing what a fan he is.
