What is your favorite childhood game?

As the title says, what is your favorite childhood game? Do you still play that game? Do you wish they'd make a remake? What makes that game so amazing to you as a child?
I'd say my favorite childhood game was either Super Mario Sunshine or Halo 3 as I spent so many hours on either game with friends finding glitches, having speedrun races, and screwing around. I wish they'd make a remake of either and I still play both today hoping I can be a kid again...
