Lots of time spent at the controls, because there were no other options at the time.
Basically all you did was hit a button to pitch and hit a button to swing. You could move around in the batters box and you just had to time the swing right to get a good hit. Popflys were easy to catch and this was really just a simple control scheme.
The thing is, I played it a lot despite the simplicity. Playing sports games with your friends and family is just always a lot of fun. And having fun is why we play games in the first place.
