Because of exclusive arrangements and wide disparities in quality, pro basketball is really the only sports title where there's genuine head-to-head competition. And it's getting nasty between 2K Sports and EA Sports.
Earlier this week, Pasta Padre found a forum post - since taken down - in which a 2K Sports representative questioned whether NBA Live 10's massive patch that went out this week deserves the praise it's getting for using community feedback. The 2K guy more or less called B.S., and said there was no way devs could have rolled out something based on community feedback and pass certification that fast, unless they were working on it prior to release. Which would imply EA Sports knew it was sending out substandard code. (Pasta Padre points out that the NBA Live 10 demo went out early, and so community feedback on the game could predate its full release.)
