Summary: MLB 10 The Show is a great baseball game for PSP. It really surprised me in the way that it featured a very solid baseball title for the PSP, it was certainly interesting but I wasn't expecting it to be this great. It's got gorgeous graphics, wonderfully detailed stadiums, professional commentary, and gameplay mechanics nearly as fine-tuned and realistic as those found in its acclaimed PS3 cousin. It is also extremely customizable.
Summary: My room mate has this on the ps3 and after years of watching him play this (and years of me owning a xbox 360) I was getting pretty desperate for the game, so I got a psp and the game. After playing it for a while, I am really happy with the purchase. It doesn't have the complete functionality of the ps3 version (of course) but it is really close! Really happy with my purchase! If you are looking for a baseball game, this is the one to get!
