Had autoaim on GTA IV PC with the Logitech F710 by default. I left it like that because I wanted to get through the main part of the game quickly. You are still able to move the reticle around. When I played Max Payne 3 I was back to the mouse and keyboard.
I was just now watching a foreign movie and I totally heard Euro Truck Simulator 2 in the background. That says a lot about realism and the state of LFS development.
