EA is being sued by consumers for their monopoly on NCAA and NFL sports-related titles and subsequent pricing.
Problem really isn't that EA bought the exclusive license from the NFL and NCAA--the problem is that when they did that, there were competing products on the market (e.g. the glorious NFL 2K5) that sold for $29.99--much less than the $49.99 (and now $59.99) that Madden sold for. Additionally, many football videogame aficionados contend that the 2K5 offering was a superior experience compared to that year's Madden title.
As a result, NFL 2K5 sales came very close to overtaking Madden until EA did two things--they lowered the price of Madden to $29.99, and they went and struck an exclusive deal with the NFL to cut 2K sports out of the market. As soon as EA obtained their exclusive deal with the NFL and 2K was left without a competing game, they jacked the price back up to $59.99.
Honestly, I'm shocked this hasn't come up sooner.
Also, rinse/repeat for the NCAA part of this lawsuit, including the same players (2K Sports, EA) in the same positions.
Additionally, some folks have said that 2K Sports (the company) is in a similar bed with MLB, but 2K has a convenient hook to their agreement in that the 1st party console owners (e.g. Microsoft, Sony, Nintendo) can obtain a MLB license and publish first party, console specific titles only. Sony is currently the only company to do this with it's MLB series, which is decidedly better than the 2K offering the past couple of years. Microsoft bought a PC baseball franchise (High Heat IIRC?) with the intent to create a competing product but instead sat on the property, and Nintendo had Ken Griffey Jr. shill a 1st party title until it was pulled during the GameCube days.
Anyone that has purchased a NCAA or NFL title from EA since their respective exclusivity deals is a possible member of the class action lawsuit IIRC.
