Whatcha mean the casual gamer won't notice? I can't walk into ANY gaming store in my area and NOT see a Zelda Pre-order poster. True, it has the Gamecube link on it, but it does have all the letters really big!
Don't take the casual gamer too lightly. (err. . . maybe not) But considering I live in a high X-box populated area (apparently the free games bargain was targeted at suburban maryland. . .) theres a lot of hype surrounding the launch. A lot more than with Metroid Prime, by the way.
And I hear the free game sale is starting soon. They'll be adds up for that in a few days, if not already. People respond to things in predictable ways. They see FREE and decided that it must be better because its the better deal.
