I like what Dungeon Keeper 2 did with the real world. It watched the clock and had special messages that it played at certain times. Midnight was always "It is the witching hour. Curses are half price." Every hour after that suggested it was time to go to bed.
What?! I didn't know that!!! *runs installing Dungeon Keeper 2* oh cant' wait untill midnight! I never played at night, that is.
