Currently I only own a Jurassic Park pro. I can't say for sure what my next pin will be let alone next four but currently...
Dialed In is at the top of the list, partially because my wife has grown to love it. But I think it's great too.
Godzilla le is a strong consideration but I'm not quite at must have, probably not my next but if I had to buy 4 more it would definitely make the cut.
3rd would be Toy Story 4 only to make my daughter happy, otherwise probably wouldn't be a consideration.
Aside from that it's a big question mark in my head as I don't have much interest in owning a game I love but have already played to death.
