On LOTR after a game is over, it plays a random music and light show (1 of 3 possibilities?) that's exclusive to the end game. Batman Forever also has a nice end of game show as well, an extension of really well done sound and light packages. I find myself being a bit mesmerized by these modes, and it gets me psyched up for another game, no matter how bad the previous game was.
It's one of those small but significant details that really adds to a game, and most likely on-location earning potential, but many games have this missing. I'm interested in hearing what other games have this and which are your favorite?
