MVP BASEBALL 2004
I bought EA Sports' new game MVP Baseball 2004. I actually like the gameplay a lot. I have been a loyal customer of Acclaim's All Star Baseball the past few years, but thought I'd give MVP a shot. I think the game play is better in MVP but the front-office features from last years All Star Baseball game have MVP beat.

Positives of MVP Baseball
Real minor league affiliates for AAA and AA
Lots of old stadiums and throwback uniforms
Game play is probably the best I've seen for PS2
Setting line-ups and rotations for minor league affiliates

Negatives
No 40 man roster (so you can send players up and down without having to clear waivers)
The game misleads you into thinking they have all the real minor leaguers when in fact they don't.
Computer will make dumb trades.

In general I'd say buy MVP Baseball 2004 if you're looking more for a game to only play (as opposed to simulate). The simulation mode is enough to get you by, but not as good as ASB 2004 (and I'd like to see ASB 2005 before I make my final decision on which game is better).
