I felt that the RTTS mode in 09 was still buggy same as 08. Strike counts were still screwed up and they still haven't made the Catcher position any more interesting. I love that position, and I would want more options as calling a pitch, setting field depth, etc etc.
One thing they had perfect was the base running controls in 08, they totally screwed that up in 09. 08 you could use the trigger buttons, to control base running of your player, but in 09 they decided to use the stupid analog stick, which made controlling you player on the basepaths next to impossible. I had to skip base running, but the game got extremely dull, because all I did was hit the ball and sat there behind the plate to receive the pitch.
I haven't checked into 10, but I hope they fixed all that otherwise, I am waiting till next year.
