Gaming sense 

The ability to sense things in games, simply because of predictable, long-standing game cliches.

My gaming sense tells me that this innocuous red barrel will explode if thrown.

My gaming sense tells me that this grave will have valuable items in it if I dig it up.

My gaming sense tells me that I'll have to fight a boss in this unexpectedly cavernous room.
