Look at it this way....
You've been out of the hobby for a decade. There have been 50+ titles released by Stern, JJP, Spooky, CGC & AP since 2012.
Just think of all the games you need to catch up on that will be new & exciting to you, while being old news to others. And all will have complete code. And probably blinged out by previous owners. And you can inspect firsthand yourself, then pick & choose what you want to buy.
Don'y jump right into the NIB rat race. You're in a great position to purchase plenty of used titles that others will be willing to let go.
