The Sinking City 2 vs The Sinking City 1 is a deliberate sequel reset, not a retread. The current title moves setting from Oakmont to Arkham, swaps Charles Reed for Cal Rafferty, shifts genre from open-world detective to semi-open survival horror, replaces the 2019 sanity meter with a resource-versus-avoidance loop, and rebuilds on Unreal Engine 5. Frogwares develops both, so the change is studio-internal evolution.
