thats sort of the thing i never do every sidequest well ok no never ever...but rarely. the game has to be damn good for me to do them all. or there have to be very few.
still the main game being short kind of sucks.
Even better for you then...beat it fast, trade it in for $42, keep your $20 cert, and keep the receipt to keep PM'ing for 2 months (if you're Silver)
