The "non game" argument

[Bodhesatva]

There we go, I like that Merriam-Webster definition even better.

1) "activity engaged in for diversion or amusement"

And I love Blue3's defense. "Brain Age is no more a game than Curling is a sport!" When there is absolutely no question that Curling is, in fact, a sport.

Not only is it defined as a sport at the very top of the page, but one should note that it is part of the Olympics.
