So that's really what I'm asking, What collectibles would you consider Canon? I know that majority if not all aren't Canon, but you could argue that for example the skull you get in Uncharted 1. As a collectible reappears as a nod and canonically in Uncharted 4IN Nathan's attic. So I would say getting that skull would be considered cannon.
But now, do you guys have a head canon of your own that they could fit canonically to the story? I heard arguments that it wouldn't make sense because Nathan has nowhere to carry them. Which makes a lot of sense since he doesn't carry a backpack.
And lastly, what type of player are you? Do you think it's more immersive when you collect them? Do you think it's worth it? Or do you just ignore them even though they're in Plainview at times? Or do you diverge path just to collect a trinket? Or do you just ignore them altogether?
