I'm with you when it's generic, way too numerous items like those damned feathers.

I'm all for collectibles when they're interesting, meaningful, and not too numerous. But I think most games and especially open world games really just want to pad the completionist time.

Horizon is a game that did collectibles much better, with the exception perhaps of data points (which aren't marked on the map for some reason). The collectibles in Horizon are unique, have story, and are usually actually interesting to get to. I noticed often in Horizon, they were just so interesting to either get to (the case for ornaments) or had fascinating story (like the ones that unlock images of the past).
