Or without the very-much-needed hold-your-breath moment at startup, where you listen to the sounds to see if the DVD actually loaded correctly. You get a ~1 second moment in there where life itself suddenly stops, before you hear the "viump" that tells you everything is OK in the world.

PS1 was more fun. You could tell it's failing to load before it failed to load. Then you give it a good smack and it tries harder before giving up. You could get almost any game disc to play reliably in 3 hits or less.
