Quoted from Jimmyhonda:I think the center post is a must have. The flipper gap in ghostbusters is wider than normal. It was documented that this was done by mistake during design/manufacturing. I would get it.
Quoted from Tomass:I thought this was speculation and not actually documented? Where is this documented, for my own knowledge? Thanks
I think I remember reading that during play testing, it was discovered that the ball drained too much down the middle, so they simply added the post instead of going back and readjusting the playfield layout, since that was the cheaper/faster option.
