What GTA-like games do you enjoy by indie devs?
The closest I can provide is Wobbly Life which is unironically an awesome physics heavy GTA-like themed around being a destructive kid.

For driving jobs, hanging out in a living multiplayer city and driving feel that hits just right check out the rabidly loved Motor Town: Behind The Wheel.

Contractville looks interesting but I haven't tried it.

Inzoi seems like it is similar in the open world roleplaying sense
