A Swing and a Miss!
There is only two different kinds of play and they're both arcade style. American and Japanese. The only difference between these two kinds of play is that one the ball gets thrown a little faster and the other the fielders are a little bit faster. Really there's not a whole lot of different between the two.
Really, there's not much depth to the game. It's too bad that one of the first baseball games for the gameboy device turned out so poorly.
