Just preordered Skyrim today from GameStop. I'll also be preordering Halo Anniversary and Assassin's Creed Revelations soon too. Honestly, I feel like it's worth it for the bonuses you get and for the joy of playing the game on release day.
On an off note, if you liked Fallout 3, why the heck don't you like New Vegas? They're nearly the exact same game, with New Vegas having a better story and better DLC, and Fallout 3 having better gameplay if only because Fallout 3's skill challenges are actual challenges and not just checks like in New Vegas.

ive always just walked into Gamestop on release day, asked forr the game i wanted, and always got one with the bonuses packed with it.
There's no way you managed to do this, since you can't get a game from GameStop on release day without a preorder. I've tried, believe me I've tried and they will not let you do it.
