Exactly! The taxi, ambulance, and firetruck missions were some of my favorite parts of the GTA games, and featured relatively nonviolent, legal activities. They could easily be standalone games... One could argue the taxi missions already are, if you count Crazy Taxi.

I always thought Rockstar should've made an EMT / first-responder version of GTA where the goal was to help rather than harm.

War Zone Taxi Driver (GTA: San Andreas with cheat codes "everyone has guns" and "everyone's hostile to everyone" applied, and me in a taxi running missions) is a really, really good game. I'd absolutely buy and play a whole game of just variations on that.
