This is another very fun action game from id software that is much larger in scope than any of their previous titles. It's been unfairly critisised for not having deeper gameplay elements but the pre launch hype and marketing was misleading with claims of similarity to Fallout 3. Rage is a fairly straight forward action game with some cool side quests and mini games: a purists FPS. The graphics, sound, overall atmosphere and mood are simply superb.
Despite what people are saying in some of the reviews here, Rage is not a buggy game. The texture 'pop in' issues were the fault of AMD who did have compatible video drivers ready for the Radeon cards when it launched. That problem is long gone and the game is silky smooth if you have a mid range card with the latest drivers (1 gb video RAM ideally).
This is an XBox game first and foremost and there are no graphics options or enhancements for PC gamers with good hardware. A pity I agree so if you have an XBox give that version a try first.
