Nah, it's just because people don't know any better.
Again, just because people buy them, does not make them good. The 2K games, particularly for Basketball and Hockey, are better games, particularly from a simulation standpoint.
Unfortunately, EA Sports has crazy brand recognition. IMO they've fallen from grace, and I do not praise them anymore for their games in the 90s, which definitely were the better games, especially compared to the competition.
