Haters gonna hate. If you can’t come to Pinside and talk about spending crazy money on Pinball where should you go?
Regarding the question at hand, maybe I missed it but are you creating the collection for just you and the wife or do you routinely have parties? What’s the demographic of those? Most will tell you that if you have other options in the game room they will get more play than the pins, if you don’t have people over much...F ‘em, get what you like. If you are picking pins for kids/noobs to enjoy get ones with evergreen themes and a bash toy in the middle with easy multi balls to get going such as TSPP.
Seems to me you like flow and most of us do. Search Pinside for best flow pins. You should play everything Steve Ritchie and pick the themes you like. No Fear, Spider-Man, Star Trek, GOT etc.
Looks like you are determined to build an amazing collection so excited to see what you come up with, keep us in the loop!
