I find myself in this camp too, especially since my wife still hasn't divulged how much she spent on our tickets for this September's show (all I know is it was over $200 per). Given the rising expense, I'm gonna need a better reason to keep going if they're just going to go with songs I've seen them play a billion times. I'd even been thinking of skipping RFYL anyway because of that reason, and then my wife said, "oh yeah, these people from work are going, so I got us tickets too." I certainly don't mind, since there are songs I've never seen them play in person, and the return of Infinite Dreams is welcome indeed. Oh, and my first time was same tour, but in 1996. Seen them most tours since then, so if RFYL is the last one, it's a good cap-off of my run.
But yeah, maybe I've got undiagnosed ADHD or something, since my excitement for Maiden tends to wane a bit if it's been a good while since they've made something new to spur said excitement. I understand if they just want to maximize crowds in these last few years by playing safe sets, but it just turns my "must go" attitude into a "we'll see" attitude.
