NBA2K21 is a video game based on the National Basketball Association. It contains various game modes such as Play Now, MyTeam, MyLeague, MyGm, and MyCareer, among others. Most of these modes contain offline and online gameplay.
 
However, the most popular mode, MyCareer, has flaws in the storyline and in the gameplay. The storyline is very generic as it has Junior go through high school and college to accomplish his dreams and make it to the NBA. You can play multiplayer on MyPark as well as offline. The gameplay is quite unrealistic for various reasons. Glitches include the basketball going through players, players getting stuck on the floor and more. A positive in NBA2K21 is an option to change the difficulty ranging from Rookie to Hall Of Fame.
 
The other modes such as Play Now, MyTeam, MyLeague and MyGm suffer from the same sense of unrealism.
 
The issue with NBA2K is that 2K Sports has no competition to make a quality basketball game. There are so many basketball fans across the world that are desperate for an NBA video game, which is how 2K Sports receive money for their game. In conclusion, I would not recommend purchasing NBA2K21 due to its various flaws.
