I'd love to see you grab the sound effects from something like the Super Batter Up for SNES. Somehow I think Bandai Namco is not monitoring the Internet for those samples -- at the very least MLB will be coming to ruin things before that happens anyway.
I can still hear those sound samples in my head, they have voice samples for: Play ball! Foul. Strike. Y'rOUT! Out. Safe! Home run!
Oh, and the ending bars of the US and Canadian national anthems. Which you could totally play just before the "Play Ball!" :)
Would also be neat to have public renditions of team songs played while the live crowd is singing.
"Go cubs go", "take me out to the ball game", etc
Yes! Will check this out for inspiration.
