One of my sons was heavily into swapping Pokeman cards when he was at junior school aged about 8, 20 odd years ago when mobile phones were in their infancy, I think. All the boys in his class were into collecting these stupid cards and the manufacturers cynically manipulated the kids by creating "rare" cards by printing very few of one particular type, thus imbuing the kids with the notion that these coveted "rare" cards were somehow valuable because there were so few of them. Many arguments and falling outs ensued, I hated the bloody craze, thought the graphics were awful. If I remember rightly a Pokeman film came out which my son pestered me to take him to, in the end some other hapless mother volunteered to take my son along with her own children, so happily I got out of that one. Can't believe Pokeman has re emerged, albeit in a more sophisticated guise.
