When I was a kid I had a blast playing Time Splitters: Future Perfect on my friend’s PS2. Such a fun game, with a great co-op story mode.

Professional work tools come to mind. Laser measures, camera gear, flashlights, 3D scanners, calculators, synthesisers, etc. Sure, there are apps that offer the same functions, but they usually lack the precision and reliability expected from professional tools. There are also some great gaming devices (such as the Analogue Pocket) that probably offer a better experience over gaming on a smartphone.
