I have a ghost busters pro in the house here. The software is really good and feels complete. There seems to be more to do than GoT, at least at first glance. The ball times are pretty short so doing those things in ghost busters is way harder.
There are a couple annoyances in the software I hope will be addressed:
1) Animations are long and cannot be double flipper skipped. None of them.
2) The left scoop fires the ball out in an evil manner often. Since the right saucer has a ball saver, I hope the left scoop can have the same ball saver. It's basically the same situation.
3) When a mode is running, and then the two brothers modes stack and the drop target pop ups come up, during the other mode, you are pretty much cock blocked from making the shots for the mode by the brothers. It would be nice if say the original mode timer could be paused while these drops are up. The result of this is you feel its a bummer to have the brothers pop up during a mode - but it should be the opposite. Mode stacking should always feel fun and rewarding not frustrating.
Of course these are just my opinions. The rules are fun, the modes provide decent variety. The lighting effects are very well done. The game is beautiful. Dwight is impressively fast for getting this much done back to back on GoT and then GB. I'm definitely getting a premium.
