MLB 08 has gone through significant improvements, and besides some graphical issues there isn't a whole lot to complain about. At this point most people know whether or not they like baseball games, so you've probably already decided whether or not you're going to purchase it.
MLB 08: The Show on the PS3 is the best possible baseball game you can buy this year, and 411 highly recommend anyone who is looking for a good sports game to try out MLB 08. The pitcher/batter dual is phenomenal, and will keep players outguessing one-another on every pitch *just like in real life*. MLB 08: The Show is a solid pick-up and will keep baseball fans entertained all season long.
