"Not much has changed since last year, but what has was done so for the better. The graphics remain nearly the same (which is a shame… why not push the Wii harder, specifically?),but there's even more varied commentary this time around, and the new MLB Life mode adds even more into the mix. You'll get more options, a bit more on the stat tracking side, even more create-a-player options (both in general, and worked into the very different Success Mode and MLB Life created players) and can still rock well over 100 hours should you so choose. Wii fans may be discouraged to find that their game hasn't come nearly as far as some expected from year to year – no online for either version, no Wii modes improved over last year, and no added Mii integration or remote play for all extra modes – but the core game is still extremely impressive, and a value that'll kick the crap out of nearly every other sports game on the market."

the score is 8.4

Well then again all the sports games come back with the same thing over and over each year with little add ons...But it looks like a good game so baseball fans might buy it...

wow, a good score for this game...

^yeah it is good,i think its as high as the last one

The life mode really seems to add a lot of value.
