There was no proper photo mode in Ratchet and Clank 2016 their "photo mode" patch was just them adding a option to hide the game's HUD and using the Plasma Striker to zoom in. Meanwhile another sony first party game Uncharted 4: A Thief's End had a actual photo mode which had came out in the same month as RaC 2016. Rift Apart does have a proper photo mode which can give Ratchet fans a glimmer of hope that insomniac is actually listening and improving.
No Multiple saves RaC2016 even after people complained about into the nexus not having multiple saves in the now closed insomniac game's forum site.
No weapon modding mechanics. When you change the armor or ship color in the extra menus. Close the game and play them game some more later. The armor and ship goes back to it's default colors. The game overall had lacked proper customization the predecessors had.
The game's length was too short and it was delayed by over an entire year.
