It's a great game. It could use one more code pass to fix some bugs and offer a few more tweaks, but it's in a good spot right now. Don't put in the center post, the game absolutely does not need it. Just learn to play it as it's meant to be played.
Ghostbusters is a challenge, but it's also extremely satisfying. It's already in my top 3 Stern machines, and it's making a strong case to stay there for a long, long time.
