I would really like some additional topper integration. I bought the topper and while I think it is awesome, I do think it is underutilized. I think it should be activated whenever you hit the spinner since that is the siren and ecto light anyway. Also the mode when you are driving ecto one to the hotel, it should run the entire time, not just at the beginning and when you make a shot. Absolutely love the game. It is a definite keeper for me.
