I love my collection right now. I'm limited to space but I feel like I've got a good mix of rules and shot layouts. I have space for 2 more but I'm waiting till I can find 2 nice EM's to put in those spots. I do like the bally/Williams pins but for some reason I just enjoy the Sterns more thus the collection. I rarely rotate games out but I do when I need something new. I'm actually in that consideration right now. Been debating on selling my Avengers to grab an Iron Maiden or maybe giving up 1 EM slot for the maiden and selling Avengers for Deadpool.

My suggestion is to mix the layouts and rules up. You don't want all fan layouts nor do you want all long playing games. Having a mix helps keep things fresher, IMHO.
