I remember being a part of a group of people on a podcast (As a listener), and one of the members said he had a code for "Super Meat Boy", and if you messaged him, it was yours. No one touched it forever, so I sent the guy a message. I couldn't run it on my computer, but he sent it to me anyway.
The other was a free copy of Penny Arcade Episode 3 that somebody posted in the gaming discussion. Needless to say, I grabbed that as well. I love the Penny Arcade Adventures. As far as console games go, My aunt bought me a copy of Mega Man Legends when I was 9 or 10. Bad....Ass...
That's all that comes to mind.
