I am currently playing Watch Dogs 2.
It's your typical open world fare but San Francisco is a fantastic setting and I enjoy the fact that the game sort of encourages you to be non-lethal and stealthy.
Sure, you can go in guns blazing, but you do it once or twice, and you feel like you're almost betraying the light-hearted spirit of the game.
So it's stun guns, melee takedowns and just avoiding the guards.
Once you get comfortable with the parkour style movements and hacking mechanics, you really feel like a bad-ass hacker infiltrating highly secure areas and causing a little mayhem in the name of hacktivist causes.
