It's not a great game. It's a decent game, with fun shooting, gorgeous art and good audio, but it's sorely lacking in content. It's a love it or hate it game.
I agree with this, most people that say its a great game; 1) know nothing about how a game should be content wise 2) do not realize that when a dev company works on a game for as long as Id did with this game, and they dropped the ball, its not a good game.
It is, as asgard said, a Decent game. I have it for the 360 and here's my honest opinion: The game starts out really good, it has a really good realistic introduction into the wasteland. The game then mellows out and if you like to explore alot of area in a campaign, this is not the game for you. 75% of the map is closed off by invisible walls and the game has you set on a very narrow path. Even the different clan bases are small and not designed very well. To call the map a "wasteland" , is one of the areas where Id screwed up because if anyone has watched a apocalypse movie or played the fallout series, a wasteland refers to a huge expanse of well, wasteland to explore. but in Rage, exploring is not what you will be doing and like i said before, the path you travel on is narrow. The graphics are good and realistic which i like alot but at some points the textures/shading take time to load which can be a trip when your moving through places quickly. The car battles in the campaign become very boring as it is the same clan cars, in the same spots, every time you move between towns.
The cars come from no-where and you cannot find where they come from. Another complaint with the game is that there is little character development and content with each clan, you merely just wipe out each clan instead of interacting or learning about them. The resistance group, which is the biggest climix to the storyline, just uses you as a job boy and you do not learn anything about any of the characters. And finally, the ending was the most disappointing ending out of any video game i have played, just read 90% of the threads on this forum about how bad the ending svcked. Overall, its a decent game but it's not worth $60 as I, and most people, can beat it in 20-30 hours even with doing all the side jobs.
