A lot of people seem to be most upset with the potential loss of ability to get the items but they could just patch in dusty token rewards for side missions or top scores in challenges.
I however really enjoyed the treasure hunts and the photo stuff was much better than expected. In a better world we would see online services expanded rather than stopped. More challenges, more activities, more props, more treasures etc. Maybe even something completely different like imagine doing challenges like mining missions vs mode or something. Or even co-op in the mining stages.
