Quoted from Scar:
I know I’m all over the place but I’m torn Ghostbusters or 2 lesser priced fun pins to start? And if lesser titles what to keep the wife and kids happy?
Not GB!!! Brutal game for newbies.
I'd say FT and JP are your two best choices for family pins, perhaps NF if the talking skull isn't scary to the kids. If you're considering newer Sterns, there's a slew of superhero and family pins that come into range at $4K (SM, XM Pro, TF Pro, POTC...etc.) that would be a lot better than GB IMO.
Edit: Also WCS went over very well with the family. We currently have ST Pro and SM for the family pins. Even something like Batman Forever or Avatar and those two games shoot entirely different. Basically get out there and play a bunch of stuff before dropping $2-4K and lugging 250+lbs around.
