Videogamer: "Like GCSEs and A-Levels, everybody seems to think games are getting easier - but the next time somebody suggests something along those lines, slap that copy of Babysitting Mama out of their fingers and show them some of the more recent titles on this list. These games are so tough they'll actually cause your hands to swell up and your brain to shutdown. We've chosen some vintage oldies from the peak of the thumb-blistering generation, too.
Be warned, however, that some of these games are too difficult for normal people to comprehend. If you feel light-headed after reading about some of these, seek professional medical advice."
