It happened three times when I defeated Ultimecia, the disk just stucked and I never see the end with my game... I saw it with my cousin though Anyway is really bad to fight Ultimecia and be praying not to beat her but for the end don't stuck!

It happened when I was playing FF7 and I was almost at the end, I was so excited, I had defeated Sephiroth (I think) I was celebrating and thinking, "Man that was easy", then the other boss came and within 3 minutes it was game over! I was pissed off!

In Tomb Raider 3 I also got like that millions of times, but there was one that was a perfect moment, I was at the 3 level, i was ridding the moto really fast and suddenly in a corner was a cobra and I screamed so much when I saw it. Lara Croft was poisoned so I just cured her, killed the cobra, put in pause and I lay at my bed coz my heart was beating very fast! I never scared so much in a game...
