If you like the old-school top-down GTA feel, American Fugitive is super cheap now and is a good-ish game. Same dev has The Precinct, which is top-down GTA but you're playing a cop.

The story is not a strong point with either, but if you need that, go to a different genre.

And there is also Rustler, which is ridiculously fun.

I also loved Simpsons Hit and Run, but that's a bit old and IDK how indie was it.
