I've played some of the other baseball games available for the PS2 and none of them even come close to touching All-Star's presentation. Again, I just couldn't get over how detailed things are - players adjust gloves, umpires stretch, and mascots dance on the dugout. During some games you'll even see planes flying over stadiums or fans placing K's on the wall. I only had two major problems with the game. The first is the crowds. Unlike the GameCube version, the crowds in the PS2 version are a jumbled, blurry mess. Also, the player collision detection leaves a lot to be desired. It was just weird to see Derek Jeter walk toward the dug out while Jason Giambi walked up to bat a swing the bat through Jeter.
The commentary is some of the best I've heard this side of a Sega Sports title. I don't know who Acclaim hired as their sound team, but these guys deserve a raise because, for once, it seems like they actually 'got it'. All-Star 2003 sounds like a real game. What I found really interesting was that the commentators weren't just limited to what was going on in the game and would often go off into little tangents about other teams in the league just like in a real game.
