2K-MLB
Sony-F1(formerly), WRC, you could also add any exclusive game from a 3rd party developer.
CM-F1
Microsoft- V8 series (if the rumor about Forza 3 is true), you could also add any exclusive game from a 3rd party developer.
Activision- Multiple deals with bands for Guitar Hero.
You could also add THQ who hold the WWE license.
Thanks for listing them up for me(👍), and I do apologize for my ignorance on the subject, but here's what I think about what you presented to me:
MLB - Exclusive amongst the 3rd party developers. And my impression is that this was done in defense, or retaliation to the EA/NFL deal. I realize that I'm not being exactly fair, but I'd say good for 2K. EA wanna play it that way, 2K can too. Really, I don't think 2K had a choice.
F1 - Yes, I'd say that is wrong. F1 is a mega franchise, and this company I've never heard of before, Codemasters, they are now on my "S" list, and I don't mean the "Super" list.
The rest - They do not really get a rise out of me, then again, wrestling has not interested me since elementary school days. Guitar Hero, smaller race series, in comparison to exclusive NFL, NASCAR, etc., I don't even consider them noteworthy.
That's my opinion. I most definitely see where you are coming from, but some of the examples provided, they seem like little league baseball to me, compared to the NFL rights. With the exception of F1 & MLB, like I said. And EA did it to take out an upcoming rival. Not the greatest example, but pretend for a second that GT and Forza was on a same console(or multi-platform, whatever). It's like GT buying the rights to all the cars, so Forza can only have cars from Chery, Tata, Daewoo, etc.
