Well this is a pleasant surprise. Will there be anything like the honor system in Red Dead 2? so many great mob stories involved having to tap dance around violence directed at police, it would be cool if there was a heavy response if you opted for an overly violent play style.
Also hoping there will be an-indepth political system. It would be cool to have the ability to bribe judges, influence elections, etc. Anything that gives some different avenues to dominating outside of brute force would be cool.
