I played Chrono Trigger (Best game of all time, if ya haven't played it, get the DS remake now) a lot as a kid, and I was terrified because I thought Lavos really would come and destroy the world in 1999. When the year 1999 did come, I was panicking because I knew that any day Lavos would awaken. But then when 2000 came and I didn't die, nor become a survivor in a dystopian world, I was utterly confused. Then it came to me! Crono and friends defeated Lavos!
