My copy of Call of Duty: Black Ops that I bought from a rental store was corrupted in that sniper scopes didn't have the black scope silhouette when zoomed in, so essentially the whole screen just zooms in.
That's kinda what happens with DNA -- a random mutation will make the resulting organism 'incompatible with life' -- or it will create a change that gives a huge advantage for survival.
My first "gaming" PC was a secondhand thing with a RIVA TNT2 M64. It had cooked memory from presumably prior abuse, in such a way that if I ran Counter-Strike with 3d accel on, some of the wall textures were transparent.
But it also relatively frequently crashed so I rarely tried using it for the better graphics, and at that young age never appreciated the cheating aspect of it.
