When RPGs have funny little comments for lots of little objects you encounter.

Little things.Bouncing tits in DOA.
Hahahaha, I love this one. Either lets me know I'm doing excellently, or I really blew it.Pile of bodies that doesn't disappear.
The pause chime in SMB1. That's mostly due to nostalgia and it being in my top 3 favorite games of all time. Also from the same game, that feeling you get when you hit the bricks just right to go to the minus world. Sometimes I turn the game on just to do that. Feels good man.

Yes, this. You just reminded me of the time I heard 2 guards talking about the Beatles in No One Lives Forever. Couldn't stop laughing for several minutes. That game and the sequel have some of the best NPC dialogue ever.- Eavesdropping in Stealth games.

Also, people citing Mario Galaxy are cheating. That entire game is happiness.
