GameVortex: Major League Baseball 2K9 Preview

GameVortex writes: "On field changes are accompanied by a number of other franchise changes. The Trading Card system is completely different. Player cards can now earn cards on both the defensive and offensive sides of the ball, so players can earn more players for their created teams. Visual Concepts sees online play as an on-going process, but has made a number of improvements to the mode. Players can share rosters and created players online or join in thirty member online leagues and tournaments".
