My problem is with the sheer amount and how much it feels like there's no thought towards getting some of them. Think of it this way: look at how the Power Moons/Korok Seeds are spread out in the maps of their respective games, and compare that to collectibles of the past that people complained about, specifically games like Banjo Tooie. I had a LTTP thread on Tooie back on GAF and I had no problems with Jiggies requiring one or two steps ahead. What I don't like is senseless placement of collectibles, which is where BOTW and SMO starts to fall flat for me. Even if you argue that it's deconstructing the whole collectibles/OCD element, there are ways of doing that without actually making the collecting seem pointless. After 500 seeds/moons, is there really a point other than flaunting that you maxed out?
At least Shrines were amazing for incentivizing going all out and collecting all spirit orbs through solving puzzles and/or combat, and rewarding you with Life Up and Stamina Up.
