he probably confused it with the list of previous releases.
anyways, just in case anyone still cares, here's the list:
brain age
tetris
tetris again
big brain academy in english
big brain academy in french
big brain academy in german
big brain academy in... something i can't identify
big brain academy in italian
big brain academy in spanish
so it really is only 4 demos, none of which are even remotely interesting.
