I seen this on another site I frequent. I thought it was a nice gesture. The man gets my approval, and if I was Todd Howard, I'd give the man the game for free just for being the first person to do it!
I've been saving caps, too. It's a little slower going, since I don't actually drink, but I'm confident the First National Bank of Travis will be ready to open it's doors when the bombs fall.
If I was Bethesda I would just give him the game, or at least send the caps back with a message saying something like "2077 isn't here yet, save your caps", or some other acknowledgement of his creativity.
