This is THE best baseball game I have ever played. The power ups are awesome (but they do get annoying at times i.e home run robbing). The innings are usually 3-5 innings long. The rookie challenge is fun and it gets you really into it. Plus in regular play you can choose how many innings you want (whether you want a quick one ore a longer one) If you love baseball, trust me it's not like slug fest, its a very great game. I strongly recommend it.
