Only decent pre-order offer has been NBA2K13's, with the somewhat exclusive for preorder Houston All-Star weekend DLC. Truth is, it's only available via code, but if you're quick and follow the entire 2K Sports crew on twitter, they might give away some All-Star codes.
And you get a good DLC for free, with a 3 point contest, a dunk contest, the all-star game and the rising stars challenge, which isn't bad.
But cars and maps? WEAK (Usually, in some cases there is some shit in this front worth checking out).
And CoD knows what's up: A game full of 12 year-olds whose parents spend way more money than that thing is worth. They gave away the map, which isn't more than a remake of a CoD:BO map, for people who preorder a 70€ game weeks before they even have a chance to play it, and since it's only for preorderers, unless they are 200% sure EVERYONE has preordered it, it has to be for private matches because guess what, your friends might have preordered it, but online randoms might have not.
What Hans Holo says about pre-order bonuses is true in most of the cases. See, I'm a big time Viper fan, and before I played Forza Horizon's demo the only way I knew I could get the 2013 Viper SRT was pre-ordering the game. I would have done it, but it was Forza or NBA, and NBA was a bit more appealing on the friends part of the deal. Later I played the demo and if you play the demo you unlock the Viper 2013, but if it wasn't like that I would have played Horizon without my favourite car, even if it's quite probably not the best in the game, nor close to being it, just because I didn't preorder. I understand what you feel, but that's your case, and in mine, some offers are quite interesting and some even worth checking out. Of course, I read the entire pre-order offer before I pre-order the game because if it's some Nuketown 2025 crap it's clear I would not preorder, and if I did it would be not for the offer, but to have the game a little earlier than the official release date (trust me, those things happen). But I didn't preorder nor think about preordering NFS:MW 12, because I saw the offer and the cars didn't actually catch my attention.
