Pretty fun, mostly a 2-person game. Definitely a bit beyond the classic pitch'n'bat games: the values of the fixed targets change with every at-bat, the ramp can disappear, there's a "no-out" pinch hitter, and you can steal (and try to throw out a steal attempt) by rapid tapping of a console button, etc. And it has a neat baseball card dispenser.
They occasionally come up for good prices; probably under $1k would be a target.
