Night Trap
Sega's Mega CD game Night Trap was the first game to ever be awarded a '15' certificate by the British Board of Film Classification (and that still applies, so don't watch it it you're under 15). Having played it, we can say that it's pretty tame. However, the use of real actors and the theme behind it probably warrants some kind of warning. I mean, this girl's in her nightie and there are men in her bedroom, drilling her neck with some strange device. We're a bit disturbed... Game over for Lisa.
