Different, but not the blissful utopia at the heart of the "noble savage" myth.
An interesting read is "War Before Civilization: The Myth of the Peaceful Savage," by Lawrence Keeley of the University of Illinois. Keeley and others have been denounced by some for having turned the myth of the noble savage into the myth of the savage savage, but I think it's not out of bounds to remember that violence wasn't born with Europeans. There have been more than enough skeletons unearthed in the southwest United States and Central America that show clear signs of violence that we can't hold to the idea that pre-European native civilization was "peaceful."
But, yes, there were differences to our civilization and, of course, differences between tribes. The tribes of the northeast US and eastern Canada tended to be more peaceful and even welcoming to Europeans at first. One theory is that they had a surplus of plenty, so to speak - lots of food, etc., and so fewer needs and less reason to be violent. On the other hand resources were more scarce in the southwest US and south of there, so there was more reason to fight.
