Are these people bloody stupid?
Like everyone has said all games have a disclaimer sheet with them as standard and Nintendo/Sega were the first dev's to actually produce them in the first place!
What kind of dumbass parent provides a games console to their kid if they know they have epilepsy anyway? what's she getting him for Christmas a Strobe and a free weekend pass to a rave?
Parents' here is a great idea!
Stop buying stuff for your kids if you are not going to investigate it first, it is your own darmn fault
