Rage raised the bar for the FPS
The only thing it raised the bar on was animations that kicked in when enemies got shot. And I really did like that, but otherwise Rage is far from raising the bar for the FPS genre.
While the game may not have added anything revolutionary to the genre id has refined it substantially
Apart from enemy reactions to getting shot, I fail to see how they refined the genre. Linear levels filled with invincible walls, horrible story (and a really disappointing ending, gameplay and story wise), underdeveloped characters, barely any destructable stuff, and nonexistent challenge at the hardest difficulty, does not make a game that has refined the genre (or raises the bar for that matter).
Its also an amazing new concept - a Single IP with futureproof graphics that can be expanded via DLC. Buy the game once, get introduced to the story & setting and then wait for the next installment to carry on your post apocalyptic adventures! I think most people that trash it don't understand this is the start of something big.
What is an amazing new concept? A post apocalyptic shooter? An IP that can be expand... milked via DLC (sure have never seen that before...). I sure am happy that I only have to buy the game once. The only story I got introduced for is that there are bad guys called The Authority, and good guys called The Resistance, go kill the bad guys. There is barely any story, and even if it's only a beginning of some kind of a story it's a piss poor beginning. DLC are way too often used as an easy way to make some quick extra money from a product, and usually add some kind of a side story that doesn't have too much to do with the bigger picture. Maybe Rage 2 will have a story that's worth something, and fix most of the shortcoming of the first one, but that doesn't make this Rage game any better.
I'm also not one of those that expected some kind of an RPG with guns like Fallout 3. And I'm not criticizing the game for being something it was never meant to be. And maybe I was a fool to think ID could actually implement a good story in their game, because they never have, but at least they could make a challenging game before this one.
