Summary: I too waited for this game instead of buying MLB Baseball at a lower price and I totally regretted it. The game play is average and very slow on transition. You can only Save and Quit in the middle of the game without the option to Save only and not to have to quit. I believe there is also a bug with the game. From time to time when the computer player do a pinch hit or any switch, the screen will freeze and it does not allow you to do anything than to reboot.
Summary: This game is a disaster. I can't believe I waited so long to get a this, when MLB is better for less money, and has been out for a long time. The load times are horrendous, and completely unacceptable. EA can do much better. But this effort lets shows why disc based games can be slow to play. I had the game for a week, and traded it in for loss. But at least now I have a baseball game (MLB) that is enjoyable and playable, without all the unnecessary wait.
Summary: While the console version is the best baseball game i have ever played, the PSP version of MVP baseball is the complete opposite. The game is very grainy and sluggish, and does not play smooth. The graphics are nowhere near the level of MLB, and the load times are forever. Hitting is nearly immpossible at even the rookie level. I had this game for under 6 hours before returning it. Although i love MVP Baseball 2005 for my PS2, the psp version is the complete opposite.
