I had a few games back in the day with my PS1 that were pressed that died... found that if dropped on the edge (even though not broken) the impact could infact distort the foil layer inside the disc... and in effect make it so the the laser could not focus... only was a problem with larger games that where written to the very outter edge... first game that did that to me was Driver (700MB game)....
