Easter eggs, we all know them in games to be little secrets that you find here and there. After playing Ratchet and Clank 3 on my PS2 earlier today I realised; theres a level named Insomniac Museum. which is practically a developer hall. it is always closed , UNLESS the time on your console is set to 1-3AM, once it is set the Museum will be open to explore, the whole easter egg in general was a clever Idea! someone who has trouble sleeping is an Insomniac, which means you'd probably up as late as 1-3AM. as well as the company that made the game is Insomniac Inc. put 2 and 2 together and your mind will be BLOWN!
