I don't agree. It won't play anything like fallout aside from it being a FPS. Its visuals are a million times better than fallout. If anything it looks closer to borderlands.
There are no character skills or progression, no character dialogue interaction, no loot collecting at all, I don't think there is crafting either.
I'd agree, Fallout and Rage are almost two entirely different games.
However, almost everything you just said in your third line (save the "no character...progression", I have no idea about this) contradicts EVERYTHING I've heard and read about this game.
But I digress, most of my info comes from this site or an article in Game Informer that's a few months old now.
It looks to me like the game will rely heavily on three things: a detailed, colorful atmosphere; an interesting and unique post-apocalyptic concept and setting; and smooth, crisp, well-refined FPS gameplay.
