I just started out today myself. It's a little hard to get into a sandbox game with my kids ruining the vibe, though, so I may need to wait until I have a bit of late night time to build a base properly and whatnot.
I've also never been a huge fan of over the shoulder perspective... I wonder if I can go first person somehow...
Well, yes, but a walking speed radar would probably fight alongside a cop, haha.
