Now, it's starting to seem like the pre-order bonus dlc madness is just spiraling out of control the last couple years now. With each retailer (best buy, game stop, target), or online service (steam, gog) offering some twinkling pre-order digital bonus to everyone willing to hand over their cash in advance.
 
Now here's the problem:
If they make it something of real value in game creating a big advantage, people who get the game later will feel ripped off, and potentially not get the game. 
But if they make it a piece of garbage, the people who pre-ordered it will be pissed off. 

So they have to sorta walk this fine line.   But usually I find they lean towards making is something purely cosmetic, or relatively useless, like something that gives you a small initial advantage, but quickly becomes useless as you quickly and easily find better gear. Because I think the pre-ordering people are less likely to complain, as they really didn't have to pay anything extra for these "bonuses". But people who get the game later, might more likely feel jilted, especially if it is any sort of multiplayer advantage.
 
Sometimes in games like Burnout Paradise, it was so shameless as to just be a series of completely non-unique codes, that anyone could look up on a website. Although sometimes they're just something of money value, like free maps you could just buy otherwise, or like Steam often does, give you a copy of an older game for free.
 
What do you guys think? Are these bonuses usually worth it to you? Do you ever feel jipped by them? Do you ever regret NOT getting in on a pre-order bonus? Do you think bonuses make sense? Is there a better way?
