I played my first couple of games on "peaceful mode", and played one on non-peaceful (in order to get the achievements for completing the game without solar power & lasers). There's .. enough complexity to the game such that I can see it'd be better to start with non-peaceful. Comparing non-peaceful mode to peaceful mode, a bit more of your time goes into setting up and maintaining defenses; but once a good set of defenses is established, playing is ~roughly~ the same as what peaceful would be. Peaceful is fun. Non-peaceful is also fun. But the powerful weapons at the end aren't as enticing on peaceful as they are on non-peaceful.
