One of the things I love about games that have such a wide range of races (especially when they can be made so uniquely individual), is how interesting it is to see their different mentalities play off from each other. This is something that you have really managed to pull of here. The use of lots of different, small things to show the contrast between the factions (from complex vs simple names to eloquent language vs guttural grunts) really helped to show the difference and support their opposite views on the use of weapons.
Very well done!
