2K Sports (Ohga Shrugs)

2K Sports is a series of Sports games developed by Sega's Visual Concepts studio. Like other sports franchises such as Konami's Pro Evolution Soccer and Electronic Arts' various sports games like Madden, 2K Sports games are released on an annual basis, with minimal changes per iteration.

Baseball
Baseball has been a 2K Sports mainstay since 2001's World Series Baseball 2K2. Since then, games in the series have been released every year, typically during March.

Football
During the Dreamcast era, the 2K series included several popular NFL games released on an annual basis. However, in 2005, Electronic Arts was granted exclusive rights to the NFL license, effectively monopolizing the genre. Since then, 2K has made no new football games.

Reception
The 2K series has generally sold decently, selling enough copies every year to ensure a minimally changed sequel the next. In recent years, the NBA games in particular have been fairly popular, especially since they have a de facto monopoly on the Basketball genre.

Critically, the various games in the series have been extremely mixed. Some titles, such as 2K's earlier NFL and MLB games and their current NBA games, are considered some of the better sports games ever made.

2K's recent Baseball games in particular have been critically panned, with the latter Dreamcast iterations in particular being considered some of the worst games of their type ever made. Additionally, 2K's NHL games, though not terribly received, are generally considered worse than EA's respective series.
