I think that might be the crux of it for a lot of people.
The only DLC I've ever won was for DC... Not a single RB track....
SillyStou: What will happen to this place when Rock Band ceases to exist?
RockBandRocker: We will all migrate to the Dance Central forums. It will be like Moses leading the Israelites out of Egypt.
Munnchy: Only Flashier, with impeccable dance moves.
RockBandRocker: With more glitter and glam. We will survive
I won the Iron Maiden pack. Didn't even want it. Wound up giving it to Cipher (one of my main RB forums regrets). I did get a few free codes from Ryan and also one from Clapton, which was cool and very much appreciated.
And I've always thought for something to be a sport it needs two things. It needs to be competitive, and it needs to require athletic ability. Poker is competitive, but does not require athletic ability = not a sport. Pro wrestling requires athletic ability, but is not competitive = not a sport. (I bring those two up only because I've seen them both called sports)
I just don't have nearly enough ****s to give to examine NASCAR in that same way, as to whether it requires athletic ability (obviously it's competitive).
