Hey KC,
I've seen the commercial for this particular item. It is one of the "Plug & Play" TV type games. Looks like a lot of fun.
They have these other games out that are just as interactive like baseball - where you actually simulate a throw of a baseball (holding a ball in hand) or swinging the bat (with a bat in hand) and all gets displayed on the TV. They have something for Tennis and Bowling as well. Difinitely fun games to occupy the kids (and ourselves!
).
