Some people wouldn’t have preordered if there wasn’t a bonus. Some people only preorder for the bonuses.
The bonuses were not free everywhere. GAME.co.uk had 2 preorders. 1 without any codes for the standard price and a “special edition” with 2 codes that cost an extra £5 - £10 (i don’t remember exactly, but it was more expensive). That’s 1 example. I’m sure they weren’t the only ones (not to mention people selling their codes on ebay and the like).
So the arguments about “the bonus is just a bonus” is not 100% true to the facts. Neither is the “you got them free” argument (not even counting full game price vs cheaper current price).
These arguments should not be used to try state why the bonus DLC should become available as they are flawed arguments.
That is not to say that they shouldn’t become available (or that they should). I do, however, like the argument put forth that likens the bonuses to limited edition items bundled with the game. If you look at it like that then it’s a collectable thing that is simply devalued by making it unlimited.
I do however also like the idea of the bonuses being sold (and preorder people getting all the bonuses free) and that money going to fund more free DLC for everyone. The problems here though are as follows: Is there a suitable way of tracking (on all three platforms) who preordered? GAME were selling “special editions” with codes long after the game was released (giving people ample time to pick up spec ops and doom packs). The other issue is this: will the sale of the bonuses actually make enough money to fund anything worthwhile?
Also: will the loss of goodwill (from the people who want to keep the bonuses limited) be counteracted by the gain in goodwill (from the people who want to purchase said DLC now)?
I haven’t heard a really good argument that convinces me that it should be released. If it would certainly fund some extra DLC then I say go for it. If not then I say it’s a collectable and if you didn’t get it you missed your chance. I only got 1 of the 4 but would have liked all 4 for completeness.
Hopefully they’ll release more collectable DLC. Then everyone can feel special. Personally I’d like that.
Specially awarded stuff that not everyone gets makes it feel more valuable. Or maybe that’s just me?
