I've already played the GTA and True Crime titles which are available for other consoles and PC, does the XBox support other good contemporary (modern age) open-world / free-roaming action game ? Example: driving, shooting, exploring the surrounding freely (by feet), action/fighting, etc... or genre-specific (like only driving, only fighting, only shooting, etc..) in a whole city to explore (with no loading screens or mission sub-divisions...)
