A PC game is a PC game anywhere in the world. How it displays it, TV out on video card or analog RBG or digital etc depends on your PC/video card and monitor.
In short if your PC is set-up to display on your home theatre TV system it will display it and work fine. If your PC is set-up to display on your 15" CRT monitor it will display it and run fine.
