2K Sports included a time-sensitive Achievement/Trophy in Major League Baseball 2K10, and the time to get it is now. Entitled "Mid-Summer Classic," the task -- good for 40 Gamerscore on Xbox Live, and a silver Trophy on the PlayStation Network -- entails playing the All-Star Game in MLB Today, which provides a videogame version of each day's slate of baseball games.
The real Mid-Summer Classic will be played tonight (July 13) at the ballpark of the Los Angeles Angels of Anaheim, Angel Stadium, and if you turn on your PS3 or 360 right now, you can play as the National League or the American League to earn your ultimately meaningless virtual reward. Presumably, you'll be able to get the Achievement/Trophy during the 2011 All-Star Game if you don't do it tonight, but why wait?
