Quoted from swampfire:Yes - Black Knight. I bought it when my son was born, and it was my first pin. He always reminds me that I can never sell it because it's his "brother".
Which is funny, because it's the exact opposite of your situation.
Mine is also Black Knight.
First game I ever bought. And sold. And bought again. And sold again. And then 2 more times.
I vowed to my wife this one would not be sold. And I have almost sold it 3 times.
