UGO writes: "Every major GTA game has released on the PC. Hell, the franchise started out on the PC! And GTA 4 is no different, and will be carjacking its way into PC owners hearts before the end of the year. So what can you expect from this version? Actually, more than you'd think.
The basics of previous GTA PC versions are there in GTA 4. Mouse and keyboard are an obvious addition, allowing you to drive, aim and run around with those two inputs. And, of course, you can plug in a controller and use that if you wish. Intriguing, though, is that you can do both at once. The game will allow you to switch back and forth between the controller and the mouse/keyboard without even needing to pause. This is great news for all the people that find driving with the keyboard a bit of a nightmare, but prefer the accuracy and response time of the mouse for aiming. Just place the controller on your lap, slide the keyboard in front of you and you're good to go."
