On the 70% price hike: that's often misquoted or listed in such a way as to give the wrong impression. Several here have made note that Madden games aren't any more expensive than they once were. You'd have to go back to WHY this deal was made in the first place in order to get that "price hike". At the time, Madden came out at its regular $50 price tag, as EA was certain it would sell as usual. However, I believe 2K's football game at the time released for like $20 or $30 brand new, and it was similar enough to Madden that a lot of fans switched over. Instead of getting $5 for last year's Madden and paying $45 for an upgrade, they just decided to pay $20 or $30.
Normally Madden wouldn't see a price drop for almost a year, but after a month EA had to drop the price of Madden to $20 or $30 in order to compete.
THEN the NFL exclusive deal happened, clearly in retaliation to EA being forced to compete for a change.
As for whether we should be angry at EA or not, I may not care about the games, but I care about the industry. With no one to compete with, EA has no reason to make improvements except for what they see fit. If there are other games that come up with better ideas, they won't get noticed because, unfortunately, everyone wants to play as their favorite teams. This is why you don't see other Football games selling too well: you can't play as your favorite team, and people want that. I don't know why, but they do.
I also look at it as a channel buying exclusive rights to air the Superbowl. What would you do if Pay-Per-View made a deal with the NFL that only THEY could air the Superbowl? Now you had to pay money in order to watch it, and they can set their rates at whatever they want. It's an unlikely scenario, but what would you think?
What makes capitalism work properly is competition. If you stomp out the competition, incentive to make a better product begins to dwindle, and you have nothing but a greedy corporation. Even Microsoft has to compete with other companies, and it's forcing them to try and make better products (laugh all you want, but anyone without a childish Anti-MS bias can tell if they actually look into the products in-depth).
For the football video games to sell best, EA should not have the right to...have the rights.....*cough*
