Up until now, a lot of what we've heard and seen with MLB 15 The Show has been centered around gameplay improvements and new features. There's a ton of them, so feel free to read about everything new here.
Today, though, Sony has a new video looking at the graphical improvements made to the game. New to this year's version are new minor league stadiums, dynamic Sun that generates shadows in real-time, and upgraded grass patterns at each MLB stadium to better reflect each ballpark's unique look.
Since we're talking about graphics, it's probabaly easier for you to just see what's new in the PS4 version of MLB 15 The Show, rather than me attempting to explain it. I'll just say one thing, it looks amazing.
