Being a huge Classic Concentration fan, I got a real kick out of the game. It was well designed, stayed true to the original format, and though "updated," it was not so modernized that it lost its identity (it even had some of the old sound fx!). It's interesting they used the best 2 out of 3 format, my least favorite of the CC formats during its run. I don't remember any other CC electronic game using the 2 out of 3 format, except the one released for the NES.
However, this all made me wonder. NBC still owns the production and distribution rights (quite obvious noting the message about licensing from Universal in the pre-game credits, and the various Universal and GE prizes in the game itself), to Concentration, IIRC, and this is an official version of the game. Would I be too optimistic to be believing NBC is not only trying to earn a buck by releasing a home game version of a format they've been doing nothing with for years, but also actually considering trying Concentration in this form out in the near future on the network?
