During an investor call today, Take-Two revealed just how nice a season NBA 2K11 has had without competition from an EA Sports' basketball sim. Hint: Really nice.

"NBA 2K11 has now sold in nearly 4 million units since launching in early October," Take-Two CEO Strauss Zelnick said during the call, "and has become the best-selling title in the history of both our basketball franchise and 2K Sports." ("Sold in," of course, refers to shipments to retailers, rather than actual purchases by consumers.)

It would be irresponsible to attribute all of the game's success to the fact that EA canceled NBA Elite 11, leaving NBA 2K11 (pretty much) unopposed in the market. 2K11 was quite well-received by critics on its own. But it would be even more irresponsible to pretend the cancellation had nothing to do with the increase in 2K11 sales.
