Dudebro is the current term for the same thing SNES gamers called the flood of new gamers that showed up with Playstation 1. Playstation 1 made gaming more mainstream when console gaming was viewed as a "basement dweller" phenomenon. SNES hardcore gamers called these playstation casuals some sort of name I'm sure. I'm talking the true gaming nerds that even owned a 3DO system.
Dudebro was slapped on the Madden yearly purchasing, CoD yearly purchasing, and Halo/GoW purchasing crowd, and has also been used as a buzzword for why new IP's are more rare and why certain franchises have seen sequel after sequel, even from differing studios (easier to have yearly releases if you stagger studios).
But ultimately it's just a buzzword for really casual gamers. Now PS3 gamers throw that term around because dudebros are not really interested in Little Big Planet, Warhawk, Uncharted, etc and they see Xbox 360 players as "dudebros".
The gamers that think Xbox Live Gold is the shit and is totally worth the money. The gamers that think Call of Duty is an Xbox exclusive franchise. And honestly I don't blame the so-called "dudebros".
Microsoft is an American company with American marketing experts who think they know what gamers want. And at the start of this generation while everyone was falling on their faces (Nintendo and Sony when it comes to internet gaming) trying to implement an internet gaming system, Microsoft came out of the gate because their original Xbox was revolutionary when it came to online gaming.
But, they rested on their laurels. They still think their marketing machine can convince everyone that Xbox Live Gold is better than the free alternative. They've forgotten everything that got them into such a great position the past 2 generations, even simple things like including headset hardware in every box. They didn't do enough research to see what their competition is doing better than them, like Playstation network now being a far better "bang for the buck" experience. They didn't consider the implications of simple things like allowing Netflix subscribers to have access to their media without a paywall.
They didn't even do the simplest thing like add BC so that Xbox 360 Gold paying members would have incentive to continue with their subscription into the next generation. (even with these draconian measures, it would have been tempting to get an Xbox One with Rock Band 3 support with all DLC playable since I've spent so much on this platform in DLC already.) But no. We can't possibly offer something to our loyal customers as incentive to keep with our platform. We'll start from scratch just like Sony.
And that's got to be the most epic fail you could have sitting next to these policies. You gave zero incentive for 360 owners to stay with your platform into the next generation. Zero. Backward compatibility with DD titles and discs would have cemented your place and would have made these policies more palatable for 360 owners. But with zero incentive to stay with you as a platform, what was accomplished by turning off so many consumers?
