Its more of becoming a better gamer really (at least for me), most games I play now have challenges but are not overly tough. Back in the N64 days I had trouble with Super Mario 64, and Ocarina Of Time. Download them now via Virtual Console and well they are really quite easy.
I do agree though to a certain extent that some games are made easier, but they are not too easy. The new feel of games is due to the new audience of gamers like already pointed out.
