What do you guys think, is this a fair system to get people to buy?

I personally have had little success with game that I pre-ordered (unless it was a consensus awesome game even before it was released), so I tend to wait until a few weeks after a game is released before shelling out the $50 or $60.

I'm not happy with only being able to get an in-game weapon or perk by pre-ordering, though I imagine I can get the perk via the internet black-market.
