im with @Dreamboum on the collectibles here. they train you to look at the space differently, and often have you looking at them for what they might hide rather than for the space itself.
think of the way Saints Row 4 or Crackdown are remembered more as obstacles courses for orbs than actual cities. that stuff can work fine with stuff like Zelda’s Korok seeds or the Mario Moons, because thats what they’re designed as, but those are very against the intent and mood of the intentionally empty spaces of SOTC.
and its because SOTC is so highly regarded that people act so negatively. think of the way people react to the changes in those original Star Wars films. they don’t change the major arcs, but they alter the tone and details in ways that are important to people. and on top of that the remake has a similar possibility to do the same thing those Star Wars blu-rays do, which is become the only available high quality version of those films and the one most people will remember.
